| 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（CEAR：Cooperative Energy Aware Routing）。协作能量感知路由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（EAR: Energy Aware Routing）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协作能量感知路由方法。仿真结果表明，相比于能量感知路由方法，协作能量感知路由方法有更好的节能性能。

| Abstract: | This paper introduces multihop diversity to the wireless sensor network for energy efficiency, and proposes a Cooperative Energy Aware Routing (CEAR) scheme. CEAR utilizes the multihop diversity to improve the classical Energy Aware Routing (EAR) scheme in the wireless sensor network. The total energy consumption at each hop in the multihop diversity procedure is analyzed, and the CEAR scheme is designed 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. |
