A Target Tracing Algorithm Based on Event-Driven WSN

Wireless sensor network(WSN)nodes are very suitable for moving target tracking tasks both in military and civilian areas.The paper studied the target tracking mechanisms based on existing research by using two-step optimum strategy that a target localization algorithm is ameliorated,and a path model selection mechanism to solve the ineffective curve-fitting problem resulted from low order curve function in position predict application.In this paper,a recover strategy after target lost is proposed.Emulation results indicated that the ameliorated target tracking algorithm had improved the effects of target localization and prediction,attained high tracing accuracy and low energy consumption results.
