Aiming at the problem of uneven of node energy consumption and leak detection in mobile object monitoring

a kind of moving objects of trajectory algorithm strategy is put forward.Monitoring node imposes the position message of the neighbor node

trajectory analysis mechanisms of moving objects and node fallback mechanism to ensure higher node utilization and coverage degree of monitoring through effective prioritization strategy

in the case of node with limited resources.The simulation results show that this strategy improves the problem of uneven distribution of node energy consumption

decreases the monitoring distortion degree of wireless sensor networks（WSNs）compared with the classic PEAS algorithm.
