چکیده

با توسعه فناوری، استفاده از شبکه‏ های مخابراتی بی سیم برای امور مختلف امری ضروری شده است. این شبکه ها یکی از امنترین و پرکاربردترین شبکه های موجود هستند که یک نمونه از کاربرد این شبکه ها، شمایی از مراقبت‏های پزشکی و نظارت بر بیمار از راه دور است. ‏ آنچه حائز اهمیت است مقوله ی کیفیت سرویس در این شبکه ها است. هدف این مقاله افزایش گذردهی بسته ها در شبکه حسگر بیسیم بدنی است و فرض شده استفاده از روش پروتکل دسترسی به زمانی (TDMA) در عدالت بسته های ارسالی و افزایش کیفیت سرویس شبکه موثر است. لذا با ارایه پروتکلی در لایه پیوند مبتنی بر اینترنت اشیا سعی شد برخی از پارامترهای کیفیت سرویس بهبود داده شود که حاصل نتایج بررسی و مقایسه این پروتکل با پروتکل های معروف در این حوزه، مشخص شد که پروتکل ارایه شده، نتایج بسیار بهتری در فاکتورهای میزان تأخیر، مصرف انرژی و توان گذردهی دارد. میزان بهبودی الگوریتم پیشنهادی در زمینه تأخیر 23.67 درصد و در زمینه انرژی 27.12 درصد و در زمینه گذردهی 10 درصد بوده است.

چکیده [English]

With the development of technology, the use of wireless telecommunication networks for the various affairs is essential. These networks are one of the safest and most widely used networks, for instance, in medical care and remote patient monitoring. What matters is the quality of service in these networks. The purpose of this paper is to increase packet transduction in a wireless body area network by assuming that the use of time-based access protocol (TDMA) method is effective in increasing the accuracy of packets and increasing the quality of network service. Therefore, by presenting a protocol in the link layer of the Internet of Things, some of the parameters of the quality of service were improved. Compared with other methods, the proposed protocol yielded better results in terms of latency, energy consumption and throughput. The proposed algorithm improvement was 23.67% in the packet delay, 27.12% in the energy consumption, and 10% in throughput.
