摘要: 针对无线传感网(WSN)中分簇路由协议在簇首分布及节点能耗不均问题,提出了一种节点能量负载均衡的分组成簇算法。根据节点能量分组,并随着节点能量的减少动态调整分组个数,组内根据能量重心进行簇首选举,利用簇首轮转和簇间多跳路由进一步均衡节点能耗。仿真结果表明,该算法有效实现了负载均衡,并显著延长了网络的稳定期。

Abstract: Concerning the inequality of cluster-head distribution and node energy consumption in Wireless Sensor Network (WSN) cluster routing protocol, a node-energy load-balance clustering algorithm was proposed. Group according to the node energy, dynamically adjust the group number to the node energy reduction, conduct cluster-head election in the group according to the energy focus, and further balance the node energy consumption using cluster-head rotate and multi-hop routing between clusters. The simulation results show that this protocol effectively balances the energy consumption among network nodes and achieves an obvious improvement in network stable period.

Key words: Wireless Sensor Network (WSN), grouping cluster, load balancing, multi-hop route, network stable period
