Abstract：It is a very important application of target tracking which is based on gery prediction in wireless sensor net ‐works .However ,a large amount of calculation and transmission which is produced by tracking target lead to high consump ‐tion of wireless sensor networks' energy .A strategy of nodes collaborative tracking based on grey prediction is proposed to solve the phenomenon that a large amount of data leads to the death of nodes prematurely ,bringing in the main communica‐tion node and main prediction node ,target position is figured out by the main prediction node ,area of nodes appearance is predicted by the main prediction .Uploading of data and node waken‐up is charged by the main communication node .Mean‐while ,a line of data communication is built up by these main communication node to avoid depleting networks' energy due to the data communication floodly .Simulation results show that the strategy can balance energy consumption and avoid death of node energy is consumpted prematurely under a certain tracking precision .
