The invention relates to a local type node management method of the wireless sensor network, which comprises the steps that at the current sampling time, a working node in a first node collection can predict that the alternative area where the ideal node combination with the optimum positioning performance at the time of the next sampling is positioned can be provided; each node in the first node collection can broadcast the forecasting information including the alternative area to other nodes in the wireless sensor network; the node which receives the forecasting information judged whether is positioned within the alternative area, and if the node is positioned within the alternative area, the node is added to a second node collection; the alternative nodes in the second node collection can mutually confirm the location and the condition of the other node, and the alternative nodes can come into the working condition at the next sampling time. The invention can effectively avoid the disadvantages that the computing load of the traditional overall type node management method is large, the storage demand is large, the complexity of the system is large, the structure is complex, the expansibility is not strong etc., the invention can rapidly obtain the node combination which can position the object with very high precision, the working complexity of the system can be reduced, and the network service life can be prolonged.
