Designing An Efficient Target Tracking Protocol Based on a Clustering Algorithm and Recovery Mechanism in Wireless Sensor Networks (WSNs

Target tracking is one of the most important and complicated applications of wireless sensor networks. In this application, temporal and spatial information of mobile object iscontinuously investigated at particular times. Energy saving is one of the main challenges in target tracking sensor networks.In this paper, we present a clustering, recovery mechanism with virtual grid and the base station as a fundamental element for target tracking in wireless sensor networks. Hence, we introduce an efficient protocol namely (NBSOTT). NBSOTT protocol tries to reduce the number of transmitted packets andsubsequently, energy consumption in order to meet the current needs of clustering. Also, using virtual grid reduces time of decision which causes to the object retaining and faster recovering. For evaluation, we compare the proposed protocol with the BSOTT and EBSOTT algorithms.
