Target tracking is one of the most important and complicated applications of wireless sensor networks. In this paper, temporal and spatial information of mobile object is continuously investigated at particular times. Energy saving is one of the main challenges in target tracking sensor networks. In this paper, the authors present a clustering, recovery mechanism with virtual grid and the base station as a fundamental element for target tracking in wireless sensor networks. Hence, they introduce an efficient protocol namely (NBSOTT).
