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 guaranteed time slot of superframe in IEEE 802.15.4. Then analyzed the performance of WSN theoretically. The analysis and simulation results show the influence of control parameters on the performance of networks, the result will provide certain basement for the application of WSN.
