基于最优分簇的能量异构无线传感器网络路由协议

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.

Energy Heterogeneous Wireless Sensor Networks Routing Protocol Based on Optimal Clustering

In order to further 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 OCRP protocol considers the optimal cluster head number K, divides the area under test into K fixed partitions, and optimizes the clustering process. In the cluster head selection stage, the residual energy of the node, the energy of the entire network and the distance between the node and the base station Distance improved cluster head election mechanism. The Simulation results show that this protocol outperforms the EH-LEACH and DEEC routing protocols in terms of extending network lifetime and energy consumption.
