In wireless sensor networks, the mobile Agent collect monitoring data of induction sensor node near anomaly target location, in order to effectively collect sensor data and reduce the spread data flow of network and reduce the energy consumption of data transmission. This paper puts forward the mobile Agent shunt data transmission technology. This technology is based on distribution rule, put the collected data back to the sink by mobile Agent in advance, and mobile Agent without carrying data continue to access the rest of the sensor nodes. The technology solved the problem of the source node energy consumption too fast due to the mobile Agent carries large amounts of data to access to source node. Experiments have been carried out to test the technology, and the experimental results show that the proposed technique can effectively prolong the service life of the source node and the implementation monitoring of anomaly target.
