Wireless Sensor Networks (WSN) are increasingly being envisioned for the collection of data, such as physical or environmental properties. Unlike detection of an event, tracking requires ensuring continuous monitoring. Resource constrained nature of wireless sensor networks makes energy efficient tracking a...
During the tracking process, the system calculates the future position that the target will move to and activates a set of sensors in advance. When the target leaves its original position, the former sensor set can go back to sleep. In this way, the system can continuously track the target...
We consider, in this work, the goal of tracking a set of targets by a sensor network (Liu and Liang, 2005). For instance, in the military case, it refers to a WSN randomly deployed in a battlefield, with one or more targets traversing the battlefield. Once activated, a sensor is ab...
Energy efficient collaborative target tracking in a wireless sensor network (WSN) is considered. It is assumed that the distance estimates of range sensors are contaminated by distance-dependent multiplicative observation noises. The nonlinear measurement model leads to the application of a generalized ...
The tracking objective is to set a non-uniform WSN coverage within the monitored domain to allow detecting the target(s) by the set of sensors. We show, in particular, how the proposed algorithms adapt to cope with obstacles. Simulation experiments are carried out to analyze the efficiency of...

Therefore, given the results of Sections 8.1 and 8.2, the use of a companion vehicle would increase the estimation accuracy significantly and also would require less demanding actions for the vehicles involved in the tracking task. Thus, this final example shows how, for scenarios where multiple ...
5 Attack in WSN Wireless network is more prone to the attack due to its dependency on the communication medium. Attacks are maliciously introduced within the network to degrade the performance. Black hole, Sinkhole, Replay, and Sybil are the commonly observed attacks in the body sensor network....
