基于IEEE802.15.4的无线传感器网络性能分析

摘要

通过将IEEE 802.15.4标准中的超帧与无线传感器网络的LEACH协议结合,在星型网络拓扑下,网络节点通过申请超帧中的GTS来进行无冲突的数据通信,对使用GTS传输数据的这一过程进行了研究,从理论上分析了无线传感器网络的网络性能.仿真结果说明了网络控制参数对网络性能的影响,为今后无线传感器网络应用中的参数配置提供了一定的理论基础.%Based on IEEE 802. 15. 4 standard, this paper combined the superframe of IEEE 802. 15. 4 with the LEACH of WSN. In the star topology the nodes would communicate without contention. It researched the communication in the guaran-teed time slot of superframe in IEEE 802.15.4. Then analyzed the performance of WSN theoretically.' The analysis and simu-lation results show the influence of control parameters on the performance of networks, the result will provide certain basement for the application of WSN.
