Abstract: Since target tracking node's selection in wireless sensor network has a significant impact on the life cycle of wireless sensor networks, therefore it proposes a tracking node selection algorithm with tracking quality assurance in this paper. First, it defines the sensory data error model which adequately quantifies sensor sensing node data errors and the probability of the node making the wrong decision within its perceived scope on the target. Secondly, it analyzes three elements wich have impact on residual energy of node lifetime, energy consumption of target tracking task execution and possibility of node sends false alarms. Finally, on this basis, it proposes target tracking algorithm with quality control. Under the premise of user given track quality assurance requirements, the algorithm selects a subset of nodes involved in target tracking and positioning tasks which maximizes the lifetime of the network, the algorithm ensures a given target tracking reliability requirements while optimizes the network lifetime. Experimental results show that: the proposed algorithm can prolong the lifetime of wireless sensor networks.
