中文摘要：
在无线传感器网络中,分簇技术可以实现高效的能量利用、方便的数据融合、灵活的网络扩展。簇首作为簇的中心,负责收集簇成员的数据,簇首消耗的能量远大于簇成员,因此,簇首的选择至关重要。提出了一种基于剩余能量的分簇协议（CPRE）,该协议优先选择剩余能量较多的节点作为簇首,并采用簇间转发的方式将数据发送到基站。仿真结果表明：该协议能够显著地延长网络的生存时间,其性能明显优于LEACH协议。
英文摘要：
Clustering techniques in wireless sensor networks can use energy efficiently,aggregate data conveniently,and expand network flexibly.As the center of clusters,the cluster heads expend more energy than the cluster members,since they have to collect data from cluster members.So the choice of the cluster heads is pivotal.This paper presents a Clustering Protocol based on Residual Energy（CPRE）.It preferentially chooses those nodes with more energy as the cluster heads and sends the data to the base station by means of inter-cluster transmission.Simulation results show that the proposed protocol achieves an obvious improvement on the network lifetime and performs much better than LEACH protocol.
