摘要

摘要: 针对无线传感器网络中突发事件监测等响应式网络应用，提出了一种基于能量的联合选举动态成簇算法。基于节点剩余能量，在事件区域内周期性地进行簇首选举，建立以簇首为根的簇树结构对事件区域内的数据进行搜集融合，从而减少网络中传输的数据量。仿真结果表明：该算法降低了节点平均能耗，具有良好的能量均衡效果，延长了网络生存时间。

Abstract: For monitoring burst events in reactive wireless sensor networks, a new United Voting Dynamic Cluster (UVDC) routing algorithm based on residual-energy is proposed. Cluster head is periodically selected according to residual-energy among the nodes located in the event area, meanwhile a structure of cluster tree rooted at the cluster head is formed within the event area to gather and aggregate data. The data transmitted in network is reduced. Simulation results show that UVDC decreases the average energy consumption, as well as balances the energy dissipation effectively, and extends the lifetime of network.
