摘 要: 随着电子技术的迅速发展,以能够检测及采集人体生理数据、应用于健康监控、医疗保健、体育竞技等 领域的体域网应用越来越广泛。但是由于人体姿态处于不停移动变化中,无线体域网的网络环境很不稳定,数据传输的 可靠性较低。针对这一问题,本文引入网络编码技术,以简化的网络拓扑为模型提出一种基于网络编解码的中继算法, 并分析了该算法的网络传输可靠性。最后,以丢包率作为网络可靠性衡量指标,仿真结果表明:该算法与传统的数据传 输算法相比,在一定程度上提高了数据传输的可靠性。

Abstract: With the rapid development of electronic technology,Body Area Network (BAN) has been widely used in detecting and collecting human physiological data,health monitoring,health care,sports and other fields.However,because the human body posture is constantly changing,the network environment of Wireless Body Area Network (WBAN) is very unstable,and the reliability of data transmission is low.In order to solve this problem,this paper introduces network coding technology and proposes a relay algorithm based on network coding and decoding,taking simplified network topology as a model,and analyses the reliability of the algorithm in network transmission.Finally,the packet loss rate is used as a measure of network reliability.The simulation results show that the proposed algorithm improves the reliability of data transmission to a certain extent compared with traditional data transmission algorithms.
Keywords: Wireless Body Area Network (WBAN);network coding;reliable data transmission
