  • To solve the node deployment problem of target tracking in wireless sensor networks (WSNs), a node deployment optimization algorithm based on k-target tracking is proposed. The algorithm considers the influence of k value, target radius, tracking angle, node communication radius and the shape of region of interest on the tracking performance of k targets. The region of interest is first divided into equilateral triangle, rectangle and hexagon models, and then the optimal side length and the tracking direction of nodes in these models are estimated. Then the location of the deployment node is estimated according to the optimal side length. Finally, according to these models, the minimum number of nodes required for k target tracking is realized. Experimental data show that the proposed algorithm can effectively track the target.
