摘要
网状拓扑结构的无线传感器网络是未来WSN发展的方向与目标,本文根据网状拓扑结构的特点,分析了该结构下WSN的优缺点,并针对网状WSN功耗消耗大、网络寿命短的不足,提出了使用网络协调器轮换机制来延长网络寿命的组建策略,从而使网络协调器始终由剩余功耗较多的传感器设备来担当。提高了网络的工作效率,增强了网络的稳定性。最后本文针对传感器设备的能量监测模块给出了具体的实现方法,通过使用DS2786电池能量监控模块实现了网络协调器的轮换,延长了无线传感器网络的寿命。
Mesh network topology is one of the key network architectures in the future. According to the feature of mesh topology, paper presents a way to increase the working time of network by taking difference devices as coordinator in turn. So the coordinator is always the device that possesses most powers in the network. This method improves work efficiency and increased stability of network. Finally, the article puts forwards a way to implement watching module for sensor device in the network. By using DS2786 watching model, the life of WSN is prolonged.
