为解决无线带状传感网中各节点能耗不均、易形成断路等问题,提出一种改进的拓扑控制方法及与之相符合的睡眠唤醒机制.在固定分簇的基础上,对簇头采用循环迁移调度机制以控制侦听/睡眠比和簇内外通信距离,并通过动态调整簇头的侦听时间以达到负载均衡.仿真结果表明,该算法能延长网络寿命,并提高网络后期监测区域完整性. In order to solve the problems of unbalanced energy consumption and easy circuit breaking in wireless sensor networks, an improved topological control method and its wake-wake mechanism are proposed.On the basis of fixed clustering, The header adopts a cyclic shift scheduling mechanism to control the listening / sleeping ratio and the distance between the inside and outside of the cluster, and achieves load balancing by dynamically adjusting the listening time of the cluster head. The simulation results show that the algorithm can prolong the network lifetime and improve the network late monitoring Regional Integrity.
