摘　　要：针对目前无线传感网络拓扑控制算法中未考虑节点能耗问题,提出基于移动Agent的无线传感网络拓扑控制策略,并采用移动Agent洪泛获取网络拓扑信息的方法。该方法由sink节点洪泛拓扑发现Agent进行拓扑发现,由拓扑汇报Agent将拓扑信息传送至sink节点,并根据节点剩余能量动态选择簇头。仿真结果表明,该方法簇头分布均匀合理,能够有效节约网络能耗。Since the wireless sensor network topology, control algorithm does not consider node energy consumption. This paper proposes a wireless sensor network topology control strategy based on mobile Agent,and adoptes mobile agent flooding method to obtain network topology information. This method floodes topology discovery Agents from sink node for topology discovery ,sends the topology information back to sink node by topology report Agents,and dynamically selectes cluster head according to node residual energy. Simulation result indicates that,with this method,cluster head distribute uniformly and reasonablely,and network energy consumption could be saved efficiently.
