英文摘要：

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.
