摘      要：Efficient target localization in Wireless sensor network (WSN) relies significantly on the Medium access control (MAC) it implements. TDMA MAC protocol is customarily used in these applications. But it only has good performance in motionless target detection, and can t cope with target-tracking detection. In this paper, a Target-tracking MAC (TT-MAC) protocol is proposed for target-tracking detection in target localization WSN. In this protocol, an energy-based clustering technique is used to achieve target-tracking detection, a sleeping mechanism is proposed for energy conservation, and a tight scheduling mechanism is proposed to reduce the latency. The protocol is compared with the cluster-based MAC protocol on Mica2 platform, and shows its superiority in energy and latency.
