Abstract: The main aim of a wireless sensor network is to provide accurate and reliable information about the area in which the sensor nodes are deployed. From the various application of a sensor network, target tracking is the recent advance. Target tracking is a challenging task due to the failure of sensor nodes because of the energy reduction, processing of data, redundancy at the sink and the mobility of the target. Path loss is another problem of a wireless network. Many algorithms have been developed to reduce the issues of target tracking. But they are note dealing with the redundancy of data at the sink due to the detection of target by multiple clusters. And multiple target tracking is the major problem that is faced by the WSN. In this paper, we present a mechanism for tracking multiple targets using a special aggregation node based on the message utility of the received signal.
Keywords: Multiple target tracking, WSN, aggregation node (AgN).
