Abstract: 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 mobileagent 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 indicatesthat,with this method,cluster head distribute uniformly and reasonablely,and network energy consumption could be saved efficiently.

Key words: wireless sensor network, topology control, mobile agent flooding, residual energy, cluster head
