摘　　要：针对无线传感器网络能量消耗不均衡并且节点电池能量有限的问题,提出了基于环扇交错的分簇路由算法,算法在簇头的确定上考虑了节点的剩余能量及与其它节点的距离,优化了簇头的选举,同一扇区的簇头采用与相邻内环的簇头之间通信的方式传输数据;并采用非均匀分簇的思想,使得靠近基站的簇的规模小于远离基站的簇的规模,均衡了无线传感器网络的能耗,通过仿真,该方法能够延长网络生存期。For energy consumption disequilibrium of theWireless Sensor Network and limit power of node bat- tery, the clustering routing algorithm based on staggered ring-fan is proposed. In determining the cluster head nodes, the algorithm optimizes the cluster head election, considering the residual energy and distances to other nodes, and the heads within the same sector of the cluster transmits data by communicating with others between the adjacent endocyclic clusters. It also adopts the unequal clustering thoughts, making the size of the cluster near base station smaller than that of far from base station, to balance the energy consumption of wireless sensor network. Simulation shows this method can prolong the network life cycle.
