Comparison of Petri Net and Finite State Machine Discrete Event Control of Distributed Surveillance Network

Free registration required

Executive Summary

Wireless sensor networks are an important military technology with civil and scientific applications. In this paper, they derive a discrete event controller system for distributed surveillance networks that consists of three interacting hierarchies - sensing, communications, and command. Petri Net representations of the hierarchies provide plant models of resource contention and internal consistency. Control specifications are derived that enforce consistency across the hierarchies. Three controllers are created using different methodologies to satisfy these specifications.
