A CA model for target tracking in distributed mobile wireless sensor network

We present a cellular automaton model that efficiently tracks a target in distributed mobile wireless sensor network. We focus on simulating the mobile wireless sensor networks for tracking a moving target considering energy-efficiency. Using the mobility of sensors, we first disperse sensors as far as possible for the better coverage while preserving connectivity. Furthermore, we introduce a tri-level alert system for activating sensors selectively. We conduct experiments for evaluating the performance of the proposed model. The performance of our model is measured in terms of lifetime, coverage and tracking quality, and compared with other models.
