Multiple Target Tracking and Data Association in Wireless Sensor Network

Target tracking is one of the most important applications in the field of wireless sensor networks. In this paper we have explored the problem of tracking multiple targets through sensor field. A number of sensor nodes are scattered in a region to detect the target. Multiple targets tracking (MTT) is more challenging than single target tracking because of different targets moving in different directions, speed variations and frequent connectivity failures of low powered sensor nodes. We have used clustering algorithm, which organizes the sensor in a wireless sensor network to form cluster. For the problem of data association arising in multiple targets tracking in the cluttered environment we have used Munkres algorithm. Through our proposed algorithm we have evaluated the performance using varying number of targets and clutters with linear filter. We have evaluated the time for each simulation, evaluated the energy performance through throughput and root mean square error during the data association using different trajectories.
