Abstract：
 This invention relates to an energy management method capable of using experienced information to layout sleep time of nodes and optimizing measurement and comunication energies based on the awaken state of nodes including: 1, a central node collects measurement information of each round of radio sensor nodes and computes the current position of a target to forecast its track, 2, when there is not target in a measurement region, the network is at the standby state, after a target enters into the region, a network node makes sure the shortest time the target entering into the region based on its forecast position and enters into a complete sleeping state in the shortest time period, 3, selecting a suitable node from being selected ones to finish actual measurement to minimize energy loss, 4, selecting part of nodes as the transfer nodes for transferring data packets to save communication energy.
