An Energy Efficient Tracking Algorithm for Reduced Coverage in Wireless Sensor Networks

Tracking includes identifying an object by its particular sensor signature and determining its path over a period of time. Due to communication, processing and energy constraints, tracking in ad hoc networks with micro sensors creates different challenges. Since existing algorithms utilized the information from all the sensors for tracking, it results in higher expenditure of energy and reduced lifetime for the network. In this paper, the authors propose to develop an energy efficient tracking algorithm for reduced coverage in wireless sensor networks. Tracking issue is first addressed through the determination of a reduced cover for the region of interest. For reduced coverage, they have used the distributed connected coverage algorithm.
