Abstract

The wireless body area network requires an optimized algorithm and protocols for the error-free communication for sports application. The communication process that takes between the hub and other nodes must be reliable and error-free without any collision. Time division multiple access is a technique in which synchronization between nodes takes place and less reliable when compared to the other multiple access techniques. This paper primarily focuses on the TDMA and Polling TDMA protocols that could be used for the communication between the nodes. Comparison of the performance metrics such as packet delivery ratio, an end to end delay, jitter and throughput gives the network reliability between the TDMA and Polling TDMA. Based on the study, various MAC techniques could be used and the latest, TDMA could be used for error-free communication, and then followed by the Polling TDMA. The Reliability of 90% was achieved using time division multiple access and was increased to 97% using Polling TDMA. This comparison can be used to propose new algorithms to find the kinematic movement of the human and also reduce the energy of the nodes.

体育应用中时分多址比较分析的轮询TDMA设计与实现

摘要

无线人体局域网需要针对运动应用中的无差错通信的优化算法和协议。集线器和其他节点之间进行的通信过程必须可靠且无错误，且无任何冲突。时分多址是一种在节点之间进行同步的技术，与其他多址技术相比，可靠性较低。本文主要关注可用于节点之间通信的TDMA和轮询TDMA协议。比较性能指标，例如数据包的传输率，端到端的延迟，抖动和吞吐量，可以提供TDMA和轮询TDMA之间的网络可靠性。根据这项研究，可以使用各种MAC技术，而最新的TDMA可以用于无差错通信，然后是轮询TDMA。使用时分多址访问可以达到90％的可靠性，而使用轮询TDMA可以将可靠性提高到97％。这种比较可以用来提出新的算法，以发现人类的运动运动，并减少节点的能量。
