This paper proposes Target Tracking with Monitor and Backup sensors in wireless sensor networks (TTMB) to increase the energy efficiency of the network and decrease the target capturing time while considering the effect of a target's variable velocity and direction. The approach is based on a face routing and prediction method. The authors use a state transition strategy, a dynamic energy consumption model, and a moving target positioning model to reduce energy consumption by requiring only a minimum number of sensor nodes to participate in communication, transaction, and sensing for target tracking.
