摘要 考虑到无线传感器网络中节点能量受限问题,提出了一种新的负载均衡的基于能量优先分簇算法的WSN分层路由协议(LRP-EPCA)。综合考虑能量因素,对LEACH协议的簇首选取机制进行改进,采用了非均匀分簇的思想来平衡簇首的能量消耗;分别以簇首和基站作为树根,生成簇内和簇间的路由树,在簇内,用分层次多跳和单跳相结合的方式将数据传输到簇首,簇首再通过多跳把数据发送到基站。仿真实验表明,LRP-EPCA协议与ECMR和PEGASIS相比,网络寿命(半数节点死亡)分别提高了200%和120%。 Considering that the energy of the nodes for wireless sensor network is limited, a novel Layered Routing Protocol Based on the Energy Priority Clustering Algorithm (LRP-EPCA) of energy consumption balance for wireless sensor network has been proposed. Taking the energy into account, we improve the selection mechanism of cluster head, and apply the idea of uneven cluster-based, which effectively balances the energy consumption among cluster heads. The Routing Trees of in-cluster and between-cluster are created by using cluster head and base station separately as roots. The data is transmitted in multi-hop of layering combined with singer-hop within the cluster and cluster-heads forward the data to base station in the way of multi-hop. Simulation results has shown that compared with another two early cluster-based routing protocols ECMR and PEGASIS, the LRP-EPCA can lead to the increase of sensor network lifetime(half nodes die) by 200% and 120% respectively.
