Two-targets tracking problem in sensor network with partial information transmission

In this paper, the sensor network with partial information transmission is introduced. Unlike existing sensor network models, the information transmission between the sensors are assumed to have an imperfect physical condition only partial information can be transmitted. Furthermore, for varying connections, the partly transmitted information can be completely distinct. The constraint on partial information transmission makes the tracking problem in sensor network more challenging. This paper deals with the two-targets tracking problem in sensor networks with partial information transmission. To reflect a more realistic situation, the interactions are assumed to exist between the targets and each sensor can only detect part of the targets' states. By employing the synchronization theory in complex network, some simple yet effective criteria are derived to guarantee the sensors track to the targets. A numerical example is utilized to illustrate the effectiveness of the proposed results. © 2011 Asian Control Association.
