Multi-target cell tracking based on classic kinetics

This article did research on multi-target tracking system based on the classic kinetics in Wireless Sensor Networks (WSN), a distributed Cell tracking model is brought up. The whole WSN was layered by Virtual Grid Architecture (VGA)[1][2]. When a target appeared in a grid, local aggregators (LA) aroused all nodes in the eight adjacent grids to compose a Cell to track target. A Cell election rule is proposed: when a target is escaping from the current Cell, based on the classical laws of kinetics and the historical track information, the position and velocity of the target can be estimated when it crossed the edge of Cell and the next Cell can be elected. Multi-Cell sequence can track multitarget concurrently. The concepts of main target and subtarget are introduced. When multi-target were space-time overlapped, a single Cell may have several main targets and sub-targets. The tracking algorithms are designed for them separately. This model can manage the problems like wrong association and missing target. The simulation showed the approach is effective.
