摘　　要：为了解决LEACH协议中簇头分布不均匀以及频繁选举簇头的问题,提出了一种分区分簇路由协议(subsection cluste-ring routing protocol,SCRP)。在SCRP算法中,节点根据基站发送的关于划分区域的消息包,加入相应的区域;在每个区域选择簇头时,综合考虑了LEACH协议中提及的阈值以及簇头的剩余能量和平均消耗能量;与基站通信时,考虑了区域内簇头的剩余能量。实验结果表明,SCRP能够比LEACH有效地延长网络的生命周期,提高基站的数据接收量。To address the problem of the uneven distribution of cluster heads and the high frequency of the head elcetion in LEACH,a new routing protocol in wireless senseor network,which is called subsection clustering routing protocol（SCRP） is proposed.In SCRP,firstly the nodes is joined into the correspording according to the messagel about the regions divided by the base station sent.When electing the heads in every region,besides the threshold referred to in LEACH,the residual energy and the average comsumption energy of the cluster heads are considered comprehensively.Communicating with the base station,the residual energy of the cluster heads in the region is taken into account.Simulation results show that,SCRP outperforms LEACH,in terms of the lifetime of network and the data received by base Station.
