Abstract: The emergence of wireless network makes tracking and locating the movable target become possible.Range-located is a popular means of target-located in the multi-sensor network.According to the information of mobile sensor nodes and the range data by apperceiving the target，in the method，the position of the target can be calculated.Then the tracked orientation of every source node can be located according to the position of source nodes and target nodes，so the target can be tracked by source nodes based on these orientation.Because the target is movable，it must recalculate its position by the isolated property，again and again，until the completion of tasks.The results of simulating experiment in MATLAB environment show that the method is more effective to track movable target by mobile source.

Key words: wireless sensors, mobile sources, track, targeting
