基于ZigBee和AODV协议的无线体域网性能仿真

摘要

作为无线传感器网络的一个重要分支，无线体域网以其巨大的应用前景，受到学术界和产业界的广泛关注。文章依据采集人体主要生理指标的传感器节点位置，采用ZigBee无线通信协议和AODV路由协议，构建了无线体域网人体模型；并通过无线网络主流仿真软件NS2仿真了基于ZigBee的无线体域网的数据传输时延和丢包率，探究了ZigBee协议对无线体域网的适用性。%As an important branch of wireless sensor networks, wireless body area network has a great application prospects. Therefore, the academia and industrial circle has paid an extensive attention to it. According to the positions of the sensor nodes which collect major physiological information of human body, a wireless body area network simulation model was built by using ZigBee wireless communication protocol and AODV routing protocol. The delay time and packet loss rate of data transmission in wireless body area network based on ZigBee were obtained through the network simulation software NS2. The applicability of ZigBee protocol used in wireless body area network was investigated.
