Most existing work on sensor network target tracking concentrates on sensor selection solely based upon one characteristics such as the sensor position or sensing modality, and not much work has been done on collecting compositive information. In wireless sensor network target tracking, there are many influencing factors and the dimensions of these factors are different. This article combines the AHP(analytical hierarchy process) and the fuzzy mathematics method fundamental theory and presents a node selection algorithm. The algorithm estimates the possible trajectory of the target and wakes the appropriate node to participate in tracking. The results of the simulation indicate that the algorithm can turn off a mass of nodes and ensure the quality of the tracking simultaneously.
