基于簇间多跳的无线传感器网络分簇算法

The Clustering Algorithm of Wireless Sensor Networks Based on Multi-Hop between Clusters

无线传感器网络节点能量受限,必须设计能量效率高的路由算法以延长网络生存时间。文章基于经典低功耗自适应分簇路由协议(LEACH),提出将簇头选取引入能量参考,簇间采取多跳与单跳路由相结合的算法(MH-LEACH),并对其进行仿真。仿真结果表明,改进后的算法在延长网络生存时间和降低能耗方面比LEACH算法有显著的提高。

By the reason of the energy of the nodes in wireless sensor networks is restricted,energy-efficient routing algorithm must be designed to prolong the network lifetime. The paper propose one new algorithm（MH-LEACH） based on classical low energy adaptive clustering algorithm （LEACH）,which selecting cluster heads with energy and multi-hop combining simple-hop between cluster. Simulation results show that MH-LEACH outperforms LEACH with prolonging the network lifetime and improving the energy utilization rate.
