چکیده مقاله :
اینترنت اشیا مفهوم جدیدی در عرصه انتقال اطلاعات، نظارت و کنترل از راه دور اشیا، موجودات و تجهیزات است که توانسته به راحتی خود را با صنایع و زیرساخت‌های مختلف سازگار سازد. انتقال اطلاعات با توجه به محیط ناهمگون اینترنت اشیا، امری چالش‌برانگیز بوده و استفاده از روش‌های مسیریابی با در نظر گرفتن محدودیت‌های پردازش، محاسبه، ذخیره‌سازی و ارتباط امری ضروری شناخته شده است. تا کنون الگوریتم‌های متنوعی با کاربردهای خاص در حوزه اینترنت اشیا و شبکه‌های حسگر بی‌سیم معرفی شده‌اند که هر یک به نحوی در رسیدن به اهداف مسیریابی موفق بوده‌اند. برخی از پروتکل‌های مطرح در این زمینه از ساختار درختی جهت جمع‌آوری اطلاعات شبکه استفاده کرده‌اند. این روش‌ها در انتخاب والد یا فرزندان گراف دچار چالش‌های مهمی وابسته به نوع کاربرد هستند. در این مقاله ابتدا یک دسته‌بندی کلی از مزایا و معایب این روش‌ها در حوزه مسیریابی اینترنت اشیا ارائه شده و سپس یک روش مسیریابی آگاه از کیفیت خدمات در مسیریابی مبتنی بر سیستم فازی پیشنهاد شده است. نتایج شبیه‌سازی و ارزیابی حاکی از آن است که روش پیشنهادی ما در آزمون‌های بهره‌وری انرژی، نرخ تأخیر و نرخ تحویل بسته نسبت به روش پایه به ترتیب 19%، 5/49% و 10% بهبود داشته است.
The Internet of Things (IOT) is a new concept in the area of monitoring information transmission and remote control of things, existents and equipment that has been able to adapt itself with different industries and substructures easily. The information transmission with regard to the non-homogenous environment of internet of things has been a challengeable topic and use of routing methods by considering the limitations of processing, calculating, saving and communicating has been known as a necessary issue. Various algorithms with special applications have been already introduced in the domain of internet of things and wireless sensor networks that each one somehow has been successful in achieving the routing goals. Some proposed protocols in this field have used a tree structure for gathering the network information. These methods in selecting the parent or children of graph are affected by important challenges depending on the type of application. In this paper, at first, a general classification of advantages and defects of recent methods has been done in the domain of routing the internet of things and then a routing method service quality awareness in routing based on fuzzy system has been suggested. The results of simulations and assessment express that the suggested method in the tests of energy productivity, delay ratio and data delivery ratio have better performance than the recent methods.
