摘要
在无线传感器网络能量消耗模型的基础上,分析了经典的分簇路由算法LEACH的不足,提出了一种高能量有效的分簇路由算法(HEHC),算法重新考虑了通信过程中的能量损耗,并依据能量因子参数优选簇首,同时使用了分簇规模约束机制。仿真结果表明,该算法能有效地减少能量损耗,延长网络的生存周期。
This paper analyzed the LEACH’s shortcomings, based on the energy consumption model in WSNs. It proposed a novel high energy-efficient hierarchical cluster-based routing protocol (HEHC) for WSNs in the aftermentioned content. HEHC presented a new strategy of cluster heads selection and cluster formation. The simulation results show that the HEHC protocol can efficiently save the energy consumption and prolong the wireless sensor network lifetime.
