Multi-target tracking using the sign of innovations in wireless sensor networks

For wireless sensor networks, target tracking is an important application areas, but the communication consumption and the lower power resource should be taken into account. Currently, the wireless sensor networks for quantitative tracking method are more concentrate on single-target tracking. This paper presents a new method based on quantitative multi-target tracking. First, in order to meet the wireless sensor networks nodes have to save power energy, and reduce communication energy consumption requirements. We introduce a new joint probability data association using the sign of innovations (SOI-JPDA), this algorithm can afford lowest energy consumption, and the performance and complexity are very close to the standard joint probability data association algorithm. Second, we propose a distributed multi-target tracking algorithm based on SOI-JPDA in wireless sensor networks. Simulation results show that this algorithm can successfully track multiple targets with minimal power consumption in wireless sensor networks.
