چکیده مقاله:
Target tracking is one of the most important applications in wireless sensor networks. In most of objects tracking sensor networks, a general method which is called clustering has beenused. The target to be tracked may go unnoticed due to problems like node failures, communication failures amongstnodes and localization errors. Recovery mechanism needs to be initiated to find the exact location of the lost target. Hence,Using Base Station, a new clustering method and new recovery mechanism with virtual grid, we introduce an efficient protocol namely (EBSOTT). Using Base Station as a fundamentalelement in tracking process, EBSOTT protocol tries to reduce the number of transmitted packets and subsequently, energy consumption in order to meet the current needs of clustering. Also, using virtual grid reduces time of decision which causesto the object retaining and faster recovering. For evaluation, the proposed protocol was compared to the BSOTT algorithm.
