In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipath fading. Then, simulation results of the exact formulas and previously respected approximate formulas are compared in MATLAB for both underlay and overlay scenarios. It is shown that the approximate formula in underlay scenario is a good estimate for exact one while approximate formula for overlaying scenario is a good approximation when the average distance between the transmit/receive nodes of D2D pair is less than half of the maximum distance between these nodes or variance of multipath fading is greater than 1.5. In addition, the probability density functions of Signal to Interference plus Noise Ratio (SINR) for underlay and overlay scenarios are found. Moreover, a new scenario is proposed which jointly considers overlay and underlay scenarios. Furthermore, exact and approximate formulas for outage probability and throughput of D2D users in the proposed scenario are derived. Finally, these formulas are compared to underlay and overlay scenarios in three special cases, low, moderate and high traffic loads Manuscript profile -

Based on the Organon-Model by Karl Buhler, Roman Jacobson (1956) distinguishes six communication functions, each associated with a dimension of the communication process. Michael Ephratt (2008) has revised the same model, considering (Eloquent) silence as a linguistic sign which conveys information in the referential, emotive, conative, phatic, metalinguistic functions. To shed light on the issue, we study several literary texts to show how communicational silence, which is a new issue in literary linguistics, and its functions are applied to transferring a message or narrating a story. It can be considered as a narrative technique in order to say something through blank, absent or deferred elements. The question of the article is how six communication functions of silence could apply to expressing something. The result of the study showed that silence has a significant role in activating reader's role in reading a text. Manuscript profile -

The aim of pluralism in status of a theoretical approach toward politics is specification and measurement of these issues; therefore, it defines politics as the arena of competition for different groups who have access to different sources; as a result, no single group can dominate others completely, and political decisions were seen as the outcomes of balance among forces and an open process. After specifying this approach in association with the democratic thought and the comparison of previous and recent conclusions of it, this article reviews its concrete implications in political order so as to assess the accuracy of its analyses in practice; therefore, in answering to this question that do the available political reality assert the theoretical hypotheses of the pluralist approach, it takes an intermediate status (depending on the kind of conclusion from pluralism).

Due to the high cost of underwater sensor nodes as well as implementation complexity, increasing the lifetime of UASNs is an important issue. Although relay nodes have an important role in reducing the transmission distance and energy consumption. But the efficient RNP (Relay Node Placement) to avoid the critical sensor nodes' elimination is the main problem, i.e., to preserve the connected network. For this aim this paper presents an innovative solution called an Efficient Relay node Setting (ERS) algorithm, which involves formulating the Relay Node Placement (RNP) as a non-convex optimization problem. Actually, due to the Difference Convex (DC) constraints the proposed RNP problem is a non-convex problem and finding an optimal solution is complicated. However, a novel transformation can be applied to DC constraints which converts the problem into its convex programming equivalent. Application of the convex programming offers the advantage of readily computing a global optimal solution. Simulation results confirm the superiority of the proposed scheme over the competing RA method in terms of network lifetime and efficiency. Manuscript profile -

The aim is to determine the optimal coefficient of non-orthogonal signal symbols and the optimal power allocation in the source-relay in order to maximize the average total rate in a cooperative communication system using the non-orthogonal multiple access technique. To achieve these goals, the average total rate of the cooperative communication system with non-orthogonal multiple access with decode and forward relay in the independent Rayleigh channel was calculated. Then, in the first step, the optimization problem of the non-orthogonal symbols coefficient is mathematically expressed for each power allocation and a closed form solution is proposed. In the second step, the power allocation optimization for the source-relay was introduced and solved. Finally, the joint optimization problem of the non-orthogonal symbols coefficient and power allocation is investigated and an algorithm proposed for the joint optimization problem. The proposed algorithm shows that the joint optimization of the non-orthogonal symbols coefficient and power allocation achieve a higher average rate than the separate optimization of each of these parameters. Also, simulations and numerical results are presented to confirm the theoretical equation, where the simulations show the 3 dB gain for the optimized system using the proposed algorithm compared to the non-optimized system.

Therefore, spatial analysis of this index is one of the basic necessities to understand the geographical changes of societies that must be carefully examined. The purpose of this article, which is applied in terms of research, is to investigate the use of ICT indicators in the cities of Khuzestan province according to the extent to which they have development indicators. The technique of collecting statistics and information in this article is using documentary and library methods and studying the official publications of the country. The statistical population of the study is 24 cities of Khuzestan province and the indicators studied in this research are 18 information technology indicators and also 31 indicators to determine the levels of their development. In this study, due to development inequalities between the cities of the province, first the cities were divided into three groups based on the indicators of development: privileged, semi-privileged and deprived. To determine the amount of digital divide between cities in each group based on the degree of ICT indicators, the PROMTEHEE technique was used. The AHP method was used to weight the indicators used in the grading. The research results show that Ahvaz and Haftkol counties have the highest and lowest levels of development indicators, respectively, and Izeh, Shadegan and Indika counties have the highest counties and Abadan, Ramhormoz and Bavi counties are the most deprived in terms of ICT indicators among other counties.

The system model consists of two multi-antenna secondary users (SU TX and SU RX), constituting the desired link and some single-antenna primary and secondary users. The objective is the maximization of the data rates of the desired SU link subject to the interference constraints on the primary users. An effective system, exploiting Transmit Beamforming (TB) at SU TX, cooperation of some single-antenna SUs and Cooperative Beamforming (CB) at them and the antenna selection at SU RX to reduce the costs associated with RF-chains at the radio front end at SU RX, is proposed. Due to the issue of MIMO channels with correlated fading, some problems arise such as inapplicability of the well-known Grassmanian Beamforming as TB scheme at SU TX. We then propose a method to overcome this problem. After formulating the problem, a novel iterative scheme is proposed to find the best TB weight vector in SU TX and best subset of antennas at SU RX, considering the correlated channel.

The system consists of a number of secondary users (SUs) in the secondary network and a primary user (PU) in the primary network. We consider the communications in the link between two selected SUs, referred to as the desired link which is enhanced using the cooperation of one of the existing SUs. The core aim of this work is to maximize the achievable data rate in the desired link, using the cooperation of one of the SUs which is chosen opportunistically out of existing SUs. Meanwhile, the interference due to the secondary transmission on the PU should not exceed the tolerable amount. The approach to determine the optimal power allocation, i.e. the optimal transmits covariance and amplification matrices of the SUs, and also the optimal cooperating SU is proposed. Since the proposed optimal approach is a highly complex method, a low complexity approach is further proposed and its performance is evaluated using simulations. The simulation results reveal that the performance loss due to the low complexity approach is only about 14%, while the complexity of the algorithm is greatly reduced. Manuscript profile -

Therefore, one of the major challenges of implementing this kind of future satellite networks is evaluation any untrusted error for the best Quality of Service (QoS). Therefore, Bit Error Rate (BER) criteria based on the type of space channel which it can be defined prefect or imperfect state between satellites and ground stations seems to be a major challenge for space communication. In this paper, the authors provide a bandwidth sharing algorithm for a proposed future satellite networks under multi-beam prototype. This structure has many antennas in transmitter and receiver sides (satellite and ground stations) which they will be communication together based on space data. Using the above framework, the coverage probability and MIMO capacity for a typical multi-beam satellite system is compared with a single antenna for satellite and multi-antenna for area side coverage based on input parameters such as path loss and Signal to Noise Ratio (SNR), respectively. Finally, the bit error rate based on imperfect channel estimation is obtained by employing 4-QAM and QPSK digital modulations and the number of antennas followed by a comparative analysis.

Vehicular ad-hoc networks are bound to play a pivotal role in communication, therefore raising the traffic in the network, using only WiFi is unlikely to address this problem. Vehicles could use SDN and other networks such as 4G as well as 5G to distribute traffic to different networks. Moreover, many approaches for handling different data types are inappropriate due to the lack of attention to the data separation idea. In this paper, we proposed a control scheme called Improve Quality of Service in DTN and Non-DTN (IQDN) which works based on vehicle communication infrastructure using SDN idea. IQDN separates data to Delay-Tolerant Data (DTD), and Delay-Intolerant Data (DID) where the former buffers in a vehicle till the vehicle enters an RSU range and sends DTD using IEEE 802.11p. DID packets are sent by cellular networks and LTE. To transmit DTD via IEEE 802.11p, the network capacity is evaluated by SDN. If that network has room to transmit the data, SDN sends a control message to inform the vehicle. Simulations show that sending data over RSU and LTE increases the throughput and decreases the congestion, so the quality of service improves. Manuscript profile -

Due to the rapid growth of population, increasing energy demand, and limited energy resources, one of the basic measures to achieve sustainable development in countries, is optimization and reform of energy consumption structures. Given that the home sector is one of the main sectors of energy consumption, one of the effective approaches in reducing and managing household energy expenditures is to use ICT capabilities. In this regard, in this study, the effect of ICT expansion on energy consumption of urban households in Iran using the Panel Data method and GLS model during the period 2008-2015 and in the form of provincial data has been analyzed. The results indicate that in some models, a significant reducing effect of ICT on energy expenditure was observed. However, in most of the estimated models, there is no significant reducing effect of ICT on household energy expenditure. It seems that the main reasons for this are the subsidy structure governing energy prices, the low share of energy in total household consumption expenditures, the lack of proper consumption culture.

Therefore, companies spend a significant amount of money each year on ICT, while not being sure that they will get a good result. The purpose of this study is to identify the dimensions and indicators of ICT performance evaluation and suggesting a model for assessing it in organizations. This research is mainly a qualitative study with a meta-synthesis approach which uses the seven-stage qualitative method of Sandelowski and Barroso to systematically review the literature to find sub-indices (codes), indices (themes) and dimensions (categories) of ICT performance evaluation. The search of scientific databases with appropriate keywords found 516 articles, among them, 89 articles were chosen finally and used for analysis. Moreover, a questionnaire has been designed and answered by ICT experts and managers to determine the importance of each of the indicators of the model. Based on data analysis, the proposed ICT performance evaluation model has three dimensions: strategic, quality, and sustainability. The strategic dimension includes indicators of organization strategy, IT strategy, and alignment. The quality dimension includes maturity, and performance indicators; and finally, the sustainability dimension includes environmental, economic, and social indicators. For each of these indicators detailed list of sub-indices (104), which are substantial for evaluation of ICT performance in organizations, were identified and explained. Manuscript profile -

The industry has been extensively changing in the worldwide. Hence, it significantly changes the business models according to the technology of new generation in digital communication. New generation technology with the emergence of creative destruction context, left the organizations by two compulsory alternatives, compliance with new system and success or destruction of the systems will be the result. Unlike many articles that considered the structural and functional analysis individually to assess the technological innovation system, the integrated process by considering structural analysis as a prerequisite of functional analysis have been applied. Literature review and industry related analysis is applied to gather eight functional factors, and also a questionnaire is designed. After data gathering, the phase of technological development analysis as a tools for prioritizing and analyzing the dependencies between the blocking functions are deployed that was rarely used in the literature. Therefore, the blocking and deriving factors are analysed and appropriate policies are made. Results show that the studied process is an appropriate framework for functional analysis and by the number of policies represented at the end, further researches are suggested. Manuscript profile -

The ability to communicate and express words is one of the possibilities that mankind has used to the highest level of history in speech and writing. Among which the arrangement of speech has always been the subject of speaker attentions. Therefore, there is a sense of purity and adornment of the speech in all the elder works. Normality is one way to understand and criticize literary issues in various aspects of the beautification of the art work in Russian Formalism School. Two ways of assimilation and succession help in the semantic normality of the poet based on the semantic rules governing the Norwegian language. Considering that the domain of meaning or semantic is more than the other levels of language in the highlighting, each poet who succeeding in terms of his talent and knowledge in this field will have more pure poems. The poet or writer is looking for a more beautiful expression while expressing the subject.In Persian linguistic studies and literary researches, the attitude of formalists has found a special place. This study examines the semantic abnormality and analyzes how to use the elements of semantic abnormality in Houshang Ebtehaj's poetry in different types of semantic abnormalities such as simile, metaphor, irony, metaphor, ambiguity, contradiction, paradox in one hundred of Houshang Ebtehaj's sonnets.

Some problems related to using these algorithm are the usage of memory of dictionary in mobile users and HLR data base as well as the ambiguity about the last location of mobile users due to delay in location updating caused by the compression algorithm. The advantage of these algorithms is reduction at the number of location updatings for a mobile user. With some modifications in the LZ78 algorithm, its problems in implementation are reduced and its usage for PCS networks is enhanced. These changes result from combining this algorithm with distance based location updating algorithm and sending symbols corresponding to some limited neighborhoods identity instead of cell number by compression algorithm For comparison between LZ78 and proposed modified algorithm, we use simulation technique. The simulation program have two structures for PCS network, namely, square cells and hexagon cell networks. For mobile users, we considered two movement pattern: one is directional and the other is omnidirectional movement pattern. The outputs of the simulation program are the number of location updating, the maximum ambiguity of user location and size of dictionary for compression algorithms. Comparing the two algorithms by simulation, we observe that in the modified LZ78 algorithm the parameters of location updating number, maximum user ambiguity and size of dictionary are lower than those in the LZ78 algorithm. At the end of the article, cost of location management of mobile user versus call to mobility ratio (the average number of call toward user to the average number of its movement) is calculated. By comparing location management for LZ78 algorithm, modified LZ78 and distance based location updating algorithm, we observe that the cost of location management is reduced for modified LZ78 compression algorithm.

In these so called multiple input multiple output (MIMO) communication systems, the algorithms used for detection of transmitted symbols are based on perfect channel state information (CSI) at the receiver side. The optimum detection approach in the sense of symbol error rate (SER) is Maximum likelihood (ML) detector. However, in the case of imperfect channel knowledge, the performance of this type of detection method degrades and symbol error rate (SER) increases. In this manuscript, we have briefly addressed the effect of imperfect channel knowledge on the performance of MIMO communication systems. Then, an analytical approach is proposed to cope with the destructive effect of CSI uncertainty on the ML detection algorithm and the performance of our proposed method is verified via computer simulations.

This paper describes a project designed to investigate and demonstrate underwater communication system in Persian Gulf for speech transmission in a real channel. At first, transmitter is designed, then channel with real data is simulated by neural network and at last receiver is designed. Transmitted data is speech signal that for more secure transmission and low frequency bandwidth, a cryptography algorithm and speech coding algorithm is applied in transmitter. Quadrature phase shift keying (QPSK) signaling is employed to make efficient use of the available channel bandwidth. In the receiver, linear equalizer and decision feedback equalizer (DFE) are tested and the best scheme is applied. Also, ray tracing method is used for simulation of sound waves propagation in Persian Gulf underwater communication channel. Manuscript profile -

Most of the activity has focused on DS-CDMA systems, in which the conventional pseudo-noise sequences will be replaced by binary chaotic sequences. Unfortunately, despite the advantages of chaotic systems such as aperiodicity, low cost generation and noise-like spectrum, the performance of most of such designs is not still suitable for multiuser wireless channels. In this paper, we propose a novel method based on singular value decomposition for adaptive multiuser detection in chaos-based DS-CDMA systems. We also propose a new genetic algorithm-based method for the optimal generation of chaotic sequences in such systems. Simulation results show that our proposed nonlinear receiver with optimized chaotic sequences outperforms the conventional DS-CDMA systems with “maximal length” codes as well as non-optimized chaos-based DS-CDMA systems in all channel condition, particularly for under-loaded CDMA condition, which the number of active users is less than processing gain.

In this paper the hybrid decode-amplify-forward protocol with best relay selection (HDAF-S)in a cooperative system with multiple parallel relays with independent non-identically channels is considered and tight upper and lower bounds on bit error rate (BER) of this protocol is derived. It is shown that the BER of this protocol outperforms the BER of amplify and forward (AF) protocol but cannot exceeds the performance of decode and forward (DF) protocol. Then through asymptotic analysis for high SNR regime, it is shown that the HDAF-S protocol achieves full diversity order. Then the BER performance of HDAF protocol with n-th best relay selection (HDAF-nS) in independent and identically distributed channels is analyzed and tight upper and lower bounds on the BER are derived. Asymptotic analysis shows that this protocol cannot achieve full diversity order and it is shown that the diversity order decreases as n increases. The analytical results are validated through simulations. Manuscript profile -

In this paper, we investigate the online resource allocation for a large class of objective functions in the EH communication systems, which are asymptotically optimal. It is shown that the solution is obtained by only considering the average EH pattern, irrespective of its stochastic dynamics. This optimal solution neither has the complexity of dynamic programming solutions, nor uses the non-causal knowledge about EH pattern. Also, some practical numerical examples for objective functions, which are utilized in communication systems, are considered and general results are derived for them. Moreover, simulation results validate our theoretical findings and show the accuracy of asymptotic theoretical curves for the transmission periods, which are used in practice. Manuscript profile -

According to recent re MoreOver recent years, green communication technology has been emerged as an important area of concern for communication research and industrial community. The reason of paying attention of this area is its effect on reducing environmental pollutions. According to recent research, a significant share of these pollutions is produced by the local area computer networks. A mobile ad-hoc network (MANET) is one of the widely used local area networks. The energy efficiency is important in MANETs not only from the green communication point of view, but also due to the network limitations in terms of battery lifetime. Of course, MANETs characterization such as distributed nature and lack of administration, nodes mobility, frequent topology changes and scare resources makes the greening trend a challenging task in such a context. In this paper, we propose and implement a green routing protocol for MANET which solves the idle energy consumption by allowing the necessary nodes and switching off the other un-utilized nodes. Simulation results show this can help to the 20 percentage of saving energy in the environment on average and also aware of the quality of service. Manuscript profile -

In such networks, the existence of a variety of cells with base stations of varying capacities and transmit powers has enabled the repeated use of available bandwidth. Moreover, the excess load on the central base station can be directed to the sub-cell base stations. In the current work, a novel approach is proposed for such a load balancing problem in which some nodes previously connected to the main base station can be served by sub-cells through the use of some D2D relays. This will increase the overall network capacity, improve the quality of service (QoS) of cell edge users, and increase covered users. In this design, the maximization of the capacity of D2D links is formulated as an optimization problem which is not convex in general. To tackle this, the main problem is divided into two sub-problems of optimal resource allocation and user-relay pairing problems with much lower complexity. Simulation results demonstrate the superiority of the proposed method over existing works addressed in the literature. Manuscript profile -

To overcome this challenge in a heterogeneous network which also suffers from the backhaul constraint, a special kind of “decoupled uplink and downlink access” policy is proposed in this paper, which let users to be served by different base stations in uplink and downlink communications. More precisely, in order to efficiently utilize the system resources, increase the users’ throughput, and guarantee the users’ fairness, a special load balancing association policy is considered in the uplink transmission and a problem which maximizes the weighted sum of users’ effective rates is solved. Simulation results show that using this association policy for the considered scenario, significantly improves the load balancing index, energy efficiency, and also users’ effective rate compared to the scenario which considers the criterion of the maximum received power of the downlink connection for both uplink and downlink transmissions. In addition we propose an algorithm which further improves the load balancing considering the backhaul constraint of the base stations and evaluate its efficiency. Manuscript profile -

By considering the nonlinear behavior of energy harvester in system design and aiming to maximize the sum of the rates, we propose an optimal method for designing energy pre-coding matrices, user information pre-coding matrices, and time devoted to the downlink and uplink phases. For this purpose, we rewrite the problem as a convex optimization problem by appropriate change of variables and propose a method to solve it. The simulation results show that in practical scenarios, employing the nonlinear energy harvesting model in the system design could reduce the transmitted energy, increase and the sum rate of the users.

So far, the semi-quantum version of many of the problems of secure quantum communication protocols has been proposed. In this study, we examined semi-quantum protocols that allow users to access a secret message directly without distributing the key. An important factor used to analyze the performance of secure quantum direct communication protocols is efficiency. In this study, the proposed semi-quantum secure communication protocol against various quantum attacks has been investigated. In the proposed scheme for decoding the confidential message by the receiver, a sequence of single photons is required, which is first generated by the controller.

The data collected by questionnaire of family communication patterns (Fitzpatrick and Ritchie, 1990) and the meaning in life questionnaire (Steger, 2010). Cronbach's Alpha was calculated to examine reliability of the measures. The power of dimensions of family communication patterns (conversation and conformity) was examined in predicting the meaning in life (presence of meaning and search for meaning) by using correlation test and simultaneous regression analysis. According to the results of this study, the dimensions of family communication patterns were able to predict the search for meaning and the strongest prediction was related to the conversation dimension (p <0.05), but the presence of meaning was not predictable by the dimensions of family communication patterns. Whereas, proper communication of family members plays an important role in creating a search for meaning in children, it can be strengthened to increase meaning in life. Manuscript profile -

The MoreThis study was aimed to investigate the mediating role of couples' communication styles in the relationship between safe and insecure attachment styles and family forgiveness in married women. This study was a descriptive correlational study based on path analysis. The statistical population included all married women in Shiraz. The sample of this statistical population was selected by the available sampling method, 202 people. Research instruments included attachment style questionnaires (Bartolomio and Horotiz, 1991), couples' communication styles (Mabler Nanali and Ekman, 2006), and family forgiveness (Pollard et al., 1998). Findings from this study indicate that attachment styles were a direct and significant predictor of forgiveness in the family. Also, couples' communication styles were able to predict forgiveness in the family. In addition, attachment styles were also significant predictors of couples' communication styles. Finally, the results showed that couples' communication styles could play a mediating role in the relationship between attachment and forgiveness styles in family. The results show that safe and insecure attachment styles and communication styles between couples are among the variables affecting forgiveness in the family and need to be considered by experts and specialists in the field of family.

The research method was correlation and structural equations. Participants in this study were 240 ninth grade male students in Behbahan, who were selected by multi-stage (relative) random sampling. The instruments used in this study were a revised version of the Fitzpatrick and Ritchie family communication patterns, the Martin and Marsh Vital Life Questionnaire, and the Pintrich and De Groot self-regulatory, cognitive, and metacognitive learning strategies scale. Confirmatory factor analysis and Cronbach's alpha coefficient were used to evaluate the validity and reliability of these instruments. The evaluation of the proposed model was performed using the structural equation method. Bootstrap method was used to test indirect relationships. The results showed that the direction of dialogue has a direct positive and significant relationship with academic vitality and self-regulated learning strategies. Also, the orientation of dialogue with academic vitality through self-regulated learning strategies has a significant indirect relationship. But compliance orientation was not directly related to academic vitality and self-regulated learning strategies and this relationship was indirectly insignificant with the mediation of self-regulated learning strategies (cognitive and metacognitive) with academic vitality. Finally, self-regulated learning strategies have a significant relationship with academic vitality. Better fit of the model was achieved by eliminating non-significant paths of compliance orientation to academic vitality and compliance orientation to self-regulated learning strategies (cognitive and metacognitive).

Therefore, they still have a desire for traditional teaching, and some management and livelihood problems of the society have caused them to not follow the use of new methods in teaching and learning. In this regard, the requirements of the age of knowledge and information and the necessity of keeping pace with the developments and achievements of technology and human sciences have been gradually felt in our country, which is evidenced by the recent decisions of the government in the field of investment for the rapid expansion of Fava in the country. Also, in order to find a suitable answer to the type of questions mentioned above, education is trying to determine a charter to guide the reforms in the country's education, which emphasizes the use of Fawa as one of its pillars. Also, in recent years, extensive activities have been carried out in the field of using information technology and FAVA in the training of strengths and development. The current research was conducted with the aim of pathology of education based on information and communication technology in elementary school. In this research, firstly, the approaches, components and strategies of Fava-based education in elementary school courses were identified, and then the pathological examination of each of the components of the Fava-based curriculum in the elementary school was done to provide a practical model in this field.

MoreCovert Communication technique is developed for LPD communication in military and civil applications. Artificial Noise (AN) is the method to confuse eavesdropper and assure data transmission. But, generating AN in wide range of frequencies and times is very challenging. Furthermore, it reveals the transmitter or challenges it for synchronization to confuse eavesdropper about environmental noise. This paper proposes a method based on Spread Spectrum as well as self-jamming as AN to solve the problems. By spreading the spectrum, we can generate AN in wide range of frequencies and times, at low power and cost-effective manner. Consequently, there is no need to synchronization. Simulation and numerical results indicate, partial band jammer, effectively confuse the eavesdropper by 1.8 dB margin at JSR = -5 dB. In the situations, transmitter and receiver may communicate at BER = 10^-3 for Eb/N > 8.3 dB. The paper simulates the proposed method for various types of jamming and reports the results where, multitone jamming is rejected for this application as artificial noise. Single-tone jammer also can confuse the eavesdropper by 2.6 dB margin at JSR = -5 dB and TRX communications quality equal to BER = 10-3 for Eb/N > 10.9 dB Manuscript profile -

Therefore, the purpose of this research is to provide a model of organizational communication in the context of remote work. The method of this research is thematic analysis. At first, 90 scientific works were identified in reliable scientific databases, and after reviewing the content related to the research, finally 30 works were directly used to determine the primary codes. To measure the validity of the research, two methods of researcher self-review and transferability were used, and for reliability, two methods of retesting and between two coders were used. Based on the analysis, a complete set of final themes including 32 primary codes, 21 basic themes, and 9 organizing themes was provided. Therefore, the factors affecting organizational communication include internal states, communication skills and social intelligence of the individual along with the level of formality and organizational complexity. In the field of organizational communication methods in the context of remote working, working from home, hybrid work and selective methods were extracted as operational methods, and open communication and interaction were extracted as communication methods. Also, two groups of individual requirements including home communication atmosphere and remote work skills and organizational requirements including human resources, political and technical factors have been proposed. Its consequences include organizational citizenship behavior, employee support behaviors, organizational identity, organizational commitment, and employee job satisfaction. Also, its implementation faces two groups of cultural and infrastructural problems. Manuscript profile
