摘　　要：为避免发生无线传感网络(WSN)能耗负载不均衡引起传感节点过早死亡现象,通过概率分区计算和能量筛选机制进行簇头选举并分簇,从而达到均衡网络能耗、延长网络寿命的目的。仿真结果表明,所提RPESA算法性能优于LEACH、SEP和EAMMH算法。In order to avoid premature death of sensor nodes caused by unbalanced energy consumption load in wireless sensor networks(WSN),cluster head election and clustering are carried out through probability partition calculation and energy screening mechanism,so as to achieve the goal of balancing network energy consumption and prolonging network lifetime.The simulation results show that the performance of the proposed RPESA algorithm is better than that of LEACH,SEP and EAMMH.
