On Wireless Sensor Networks Formal Modeling Based on Petri Nets

A kind of intelligent wireless sensor networks (IWSN) is set up from the point of view of multi-agent systems. IWSN is composed of some sensor node agents, some cluster head agents, a base agent and a command agent. According to the characteristics of these agents, intelligent wireless sensor networks model (IWSNM) based on Petri nets is proposed, which can accurately and unambiguously model the overall and individual characteristics of the networks. Moreover, IWSNM can be analyzed, verified and validated by the supporting tools of Petri nets. Consequently, the defects in early design stage can be detected, and the security and reliability can be improved. Finally, IWSNM are employed to develop the target tracking systems.
