To develop effective multi-target tracking system in wireless sensor networks (WSN), researches have been made on the collaborative signal processing (CSP) model and the load balancing tree(LBA). An event triggering multi-target tracking model based on dynamic cells is brought up. In this paper, the entire region is divided into grids. As a target appeared, the nearest local aggregator(LA) awoke all nodes in adjacent eight grids to compose a cell. Then the cell began tracking target. Multi-cell can tracking multitarget independently and simultaneously. The paper defined main target and sub-target and divided multi-target tracking into three situations: non-intersection targets, intersection targets with partially overlap cell, intersection targets with completely overlap cell. The simulation result proved that the algorithm is timely and effectively.
