Abstract

Problem statement: Due to communication, processing and energy constraints, tracking in sensor networks 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. Approach: We propose to develop a distributed coverage and target tracking algorithm for wireless sensor networks. Tracking issue is first addressed through the determination of a reduced cover for the region of interest. For reduced coverage, we have used the distributed connected coverage algorithm. We propose a target zone detection algorithm to estimate the locations of the targets from the sensors within the target zone. The locations of the sensors are estimated by the localization algorithm. Results: This is performed with the unknown location information by utilizing the knowledge of the positions of the sensors and inter-sensor measurements. Conclusion: By simulation results, we show that the proposed algorithm achieves reduced energy consumption and coverage along with delay.
