无线传感器网络能量异构非均匀分簇路由协议

Energy heterogeneous unequal clustering protocol for wireless sensor networks

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。

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 protoco（lEHUC）.The network simulation results show that the protocol can be effectively used in heterogeneous network and prolong the network life cycle.
