数据聚集技术是无线传感器网络的一项重要的支撑技术。在数据聚集技术基础上,提出基于移动代理中间件的无线传感器网络数据聚集方案。以层簇式拓扑结构,分析了节点能量的消耗,给出实现数据查询任务的派发算法和数据查询结果的收集算法。仿真实验证明该方案能有效的节省网络能量耗损,延长网络生存周期。

Data aggregation is an important supporting technology in wireless sensor networks （WSN）. On data aggregation technology,the paper puts forward data aggregation plan based on mobile agent middle-ware in WSN. By presenting hierarchical topological structure, it analyzes the energy consumption of nodes. What＇s more,it provides the dispatching algorithm to accomplish the tasks of data inquiry and the collecting algorithm to search the results of data inquiry. Simulated experiments prove that this plan can effectively save energy comsamption and extend the life circle of network.
