摘　　要：将多跳分集引入无线传感网中以节能,提出协作能量感知路由方法(cooperative energy aware routing,CEAR)。CEAR方法利用多跳分集方法对无线传感网经典的能量感知路由(energy aware routing,EAR)方法加以改进,分析了多跳分集方法中各跳的总能耗,并基于能耗分析结果设计CEAR方法。仿真结果表明,相比于能量感知路由方法,CEAR方法有更好的节能性能。This paper introduced multihop diversity to the wireless sensor network for energy efficiency,and proposed a coope-rative energy aware routing（CEAR） scheme.CEAR utilized the multihop diversity to improve the classical energy aware routing（EAR） scheme in the wireless sensor network.Analyzed the total energy consumption at each hop in the multihop diversity procedure,and designed the CEAR scheme based on the analysis results of the energy consumption.The simulation results show that the CEAR has the better energy efficiency than the EAR scheme.
