摘要
目前针对数据融合的分簇路由缺少合理的分簇依据,可能会造成多余能量的消耗。为此,提出一种基于能耗模型的优选分簇树型路由构建方法。由经典树型能耗模型证明网络优选分簇理论的存在性,基于该理论给出优选分簇数据融合树算法,从而实现簇树路由的构建。仿真结果表明,该方法能提高网络整体能耗,延长网络生存周期。
Data aggregation can obviously cut energy consumption .of Wireless Sensor Network（WSN）, but there is no reasonable clustering solution which may cause more energy cost form the beginning. Aiming at the problem, this paper proposes a cluster-tree routing construction method based on energy consumption model in WSN. It proves the exist of optimal-clustering based on this model, gives the Optimal Energy Aware Cluster Tree（OEACT） algorithm, and realizes the construction of cluster-tree routing. Simulation results demonstrate that the method can improve the whole energy consumption of network, and increase the lifetime of the network.
