Collaborative signal processing cluster-based for target tracking in wireless sensor network is proposed in this paper. Node clustering is a useful approach to reduce the communication overhead and develop data fuse in wireless sensor networks. Each sensor node, which has incomplete information about its dynamic and uncertain world, must respond to sensed events within time constraints. The aim of...
Target tracking application in WSN should solve the problem of target status sharing well. To overcome the shortages of DCTC and cluster-based method, method using connected dominating set based aggregation tree is introduced. According to whether node has the capability of locating, target status information can be shared in aggregation tree by broadcast or unicast. Because of the structure stability...
Target tracking is one of the popular applications of wireless sensor networks (WSN). Randomly distributed sensor nodes(motes) in environment gather spatio-temporal information about target(s) and send them to a sink node for further processing. Motes like personal computers use low cost crystal based clocks. In order to maintain synchronization accuracy to acceptable levels, we shall need to synchronize...
In this paper, we address the problem of distributed tracking of a maneuvering target using sensor networks with nodes that possess limited sensing range (LSR). In such sensor networks, a target can only be observed by a small percentage of the sensors and is practically hidden to the remaining majority of the nodes. This feature is shared among most of today's wireless sensor networks and differentiates...
In this paper, the problem of fully-decentralized data fusion is addressed for tracking a target with nonlinear motion model. The problem is solved by applying a fully-decentralized estimation algorithm based on the extended information filter. We propose the neighbor selection and information selection algorithms for sensor selection based on their closeness to the estimated target position and their...
Multi-target tracking is an important embranchment of WSN. This paper works on data fusion of multi-target tracking. We choose LEACH by Wook Choi et al. (2004) as the routing protocol, and FCM algorithm to do association in cluster heads. Based on analysis of former FCM, we found a few problems about it. Such as miss association, missing new targets and repeat tracking of targets. We proposed some...
