摘　　要：为了进一步均衡网络能耗,延长网络生命周期,提出了一种基于最优分簇的能量异构无线传感器网络路由协议(OCRP)。OCRP协议考虑了最优簇首数K,将待测区域划分为K个固定分区,优化了成簇过程;在簇首选择阶段,充分考虑了节点的剩余能量、整个网络的能量以及节点与基站之间的距离,改进了簇头选举机制。仿真结果表明,该协议在延长网络寿命和能量消耗方面的性能优于EH-LEACH和DEEC路由协议。In order to balance network energy consumption and extend network life cycle,a routing protocol based on optimal clustering for heterogeneous wireless sensor networks（OCRP） is proposed. The optimal cluster head number K is considered in OCRP,and K fixed partitions are divided in the area under test,as well as the clustering process is optimized. In cluster head selection stage,the residual energy of the node,energy of the entire network and distance between node and the base station are considered as decision factors to improve cluster head election mechanism. Simulation results show that the performance of OCRP is better than EH-LEACH and DEEC in terms of extending network life and energy consumption.
