LEACH协议和PEGASIS协议是典型的分层路由协议,但是也有各自的不足。在LEACH协议中会出现分簇不均的问题,而PEGASIS协议中,算法会导致长链,Leader的选举策略使节点能量消耗不均匀,并且还有拓扑重构的问题。基于LEACH协议和PEGASIS协议提出了一种新协议,该协议通过均分区域避免长链和分簇不均,以剩余能量最大的节点作为Leader节点的策略避免节点能量消耗不均,采用刷新路由表的方式避免拓扑重构。仿真实验的结果表明,本协议在均衡节点能量消耗和延长网络寿命方面能取得更好的效果。

LEACH protocol and PEGASIS protocol are classic hierarchical routing protocol, both of them have short- comings. In LEACH protocol, clustering is uneven. In PEGASIS protocol, its algorithm will generate long-chain be- tween neighboring nodes, the election strategy of the Leader node will cause the uneven energy consumption of the nodes in the WSN, and the topology will be reconstructed. Based on LEACH protocol and PEGASIS protocol, a new protocol is proposed in this paper. The new protocol can avoid long-chain and the problem of uneven clustering by the region of equi-partition. The election strategy of Leader whose residual energy is maximum can avoid uneven en- ergy consumption. By refreshing the routing table, the reconstruction of the topology can be avoided. The simulation results show that the new protocol has better performances than the two kinds of classic protocols in balancing the nodes energy consumption and extending the network life.
