Abstract
Energy-efficiency is an issue that needs to be considered while designing a scheme for target tracking. The purpose of this paper is to propose a scheme for target tracking that mitigates the power consumption. The proposed scheme consists of a dynamic leadership delegation based activation algorithm for efficient target tracking. A dynamic activation range for awaking sensors in the neighborhood of the target is used depending on its speed. The effectiveness of the proposed scheme is analysed through extensive simulations. The performance of the proposed approach is observed to be better than the existing approaches in terms of the accuracy of tracking and the amount of power consumption.
