Sensor Selection Heuristic in Sensor Networks

We consider the problem of sensor selection so as to minimise error in estimated location of target. An algorithm based on selecting a sensor in a direction in which the error is minimized has been proposed. The ideal direction is obtained by minimising one of the measures obtained from the intersecting region of the error annuli. The algorithm has a linear computational complexity and is better suited in comparison with the information theoretic approaches. We have addressed the problem of finding out an average number of sensors after which there is no improvement in the accuracy of estimated location.
