Abstract: To reduce the energy consumption of sensor nodes and prolong the lifecycle of the wireless sensor network，the anycast technique is brought into the mobile agent routing algorithm，and a mobile agent anycast routing strategy is put forward.In this strategy，the diversity and self-adaptation characters of artificial immune system are used to find out the optimal data source access order，then an anycast algorithm based on energy restrictions is used to select a node in multiple sensing nodes of a data source.MA migrates in the nodes which satisfy the energy conditions.Simulation results show that the proposed strategy can minimize the cost to access the data sources and use the energy of nodes equably.Then the strategy can prolong the lifetime of WSN effectively，and has preferable common use character.
