چکیده مقاله :
با گسترش و همهگیر شدن اینترنت اشیاء، در آیندهای نهچندان دور شاهد وابسته شدن زندگی بشر به سرویسهای آن خواهیم بود. در آن زمان تصور ادامه حیات بدون اینترنت اشیاء دشوار بوده و بروز اختلال در سرویسهای آن موجب وقوع خسارات جانی و مالی بسیاری خواهد شد. بروز اختلال در سرویسهای اینترنت اشیاء میتواند به دو علت پیش آید: اختلالات شبکه و اختلال ناشی از انجام فعالیتهای مخرب نفوذگرها. فعالیتهای مخرب نفوذگرها همچنین میتواند منجر به نقض حریم خصوصی افراد شود. در این مقاله راهکاری برای افزایش مقاومت سرویسهای اینترنت اشیاء در برابر اختلالات شبکه و فعالیتهای مخرب نفوذگران ارائه شده است. راهکار پیشنهادی با اتکا بر قدرت پردازشی نودهای حاضر در لایه مه، بهصورت توأمان به کاهش تأخیر (بهبود کیفیت) سرویس و بهبود امنیت و حفظ حریم خصوصی اشیاء میپردازد. سایر ویژگیهای راهکار پیشنهادی عبارت از رعایت عدالت میان اشیاء از منظر کیفیت سرویس دریافتی و حداقل نمودن سربار ناشی از پردازش و انتقال بستههای منقضی (بستههایی که قطعاً تأخیر بیش از حد آستانه را تجربه خواهند نمود) است. رعایت عدالت موجب میشود کیفیت سرویس هیچیک از اشیاء قربانی کاهش تأخیر سرویس کل شبکه نشود؛ چراکه ممکن است اشیاء مذکور مورداستفاده در کاربردی حیاتی (مثلاً در حوزه سلامت) باشند.
As the Internet of Things (IoT) expands and becomes more widespread, we will soon see the dependence of human life on its services. At that time, it would be difficult to imagine the survival without the IoT, and disruption of its services would cause great loss of life and property. Disruption of IoT services can occur for two reasons: network errors due to congestion, collision, interruption and noise, and disruption due to the malicious activities of infiltrator. Also, the destructive activities of infiltrators can lead to various cyber attacks and violation of the privacy of individuals. Therefore, before the interdependence between human life and IoT, it is necessary to consider measures to ensure the quality and security of service and privacy. In this study, a solution to reduce service delay (improve quality) and ensure security and privacy of things by relying on the computing power of nodes available in the Fog Layer has been proposed. The proposed solution simultaneously improves service quality and maintains security and privacy. Other features of presented algorithm in proposed solution of fairness between objects are in terms of the quality of service received and minimizing overhead processing and transfer of expired packages (packages that will certainly experience a consumedly threshold delay). Adherence to fairness ensures that the quality of service of any of the things does not be a subject of the reduction of the delay of the service of the entire network; These aforementioned objects may be subjects of critical applications, such as health.
