“…A computable lower bound on the optimal trade-off between energy consumption and tracking performance is presented, and strategies that come close to this bound are presented. Furthermore, it is shown by Fuemmeler & Veeravalli [133] that the nearly optimal strategies result in considerable savings in energy over [134], and sleeping policies for under general models for object movement, object sensing and tracking cost are presented by Fuemmeler et al [135].…”

“…A kernel P is defined such that P(x,y) is the probability that the next state is y.Here the current state is termed to be x.Then "t" time steps towards the future is predicted by the equation by defining P1=P inductively as in [10] In order to provide the means of centralized control, extra node called as centralized controller is assumed [10]. This controller keeps track of the state of the network and it is responsible for assigning sleep times for the sensors that are awake [10]. For a time period of one unit, each sensor is assumed to remain awake.…”

“…As the Battery life of the sensor decreases corresponding variations also reflect in the energy cost. M athematical representation of the energy cost is represented as [10] Tracking error: The tracking error is also addressed as the cost which can further be subdivided into two components. They are observation error and data association error.…”

“…Due to difficulties of a centralized processing to handle multi-target problems, the authors in [4] have studied the tracking problem by a distributed data processing approach. In [5] a special scenario is considered in which sensor nodes can be put into a sleep mode with a timer, that determines the sleep duration. By optimizing the sleep duration they show an improvement of the tracking performance in sensor networks.…”

“…By optimizing the sleep duration they show an improvement of the tracking performance in sensor networks. In contrast to [4] and [5], we investigate the centralized scenario and determine the least reliable sensor nodes to keep them asleep for a uniform time duration, respectively. It is to mention, that our approach is more general and it can be used not only for tracking but also for detection and classification of targets, cf.…”
