Abstract: A cluster-based routing protocol for wireless sensor networks with multi-hop routing method transmits data to the base station，easily close to the base station nodes forwarding a large number of data are premature failure.In addition，clustering protocol usually assumes that the network node is the energy isomorphism，is can not effectively solve the energy problem of heterogeneous nodes.As a result，the article from the unequal clustering point of view，combined with local cluster head competition mechanism，presents an Energy-based Heterogeneous Clustering protocol（EHUC）.The network simulation results show that the protocol can be effectively used in heterogeneous network and prolong the network life cycle.

摘要： 基于分簇的无线传感器网络路由协议，采用多跳路由方式传输数据至基站，容易造成靠近基站的节点转发大量数据而过早失效。另外，分簇协议通常假定网络节点是能量同构的，不能有效解决节点能量异构的问题。因此，从非均匀分簇的角度出发，结合局部竞争簇首机制，提出了一种基于能量异构的分簇协议（EHUC）。仿真结果表明该协议能够有效应用于能量异构的无线传感器网络，并延长网络的生命周期。
