Architectural Design, Behavior Modeling and Run-Time Verification of Network Embedded Systems

There is an increasing need for today’s autonomous systems to collaborate in real-time over wireless networks. These systems need to interact closely with other autonomous systems and function under tight timing and control constraints. This paper concerns with the modeling and quality assurance of the timing behavior of such network embedded systems. It builds upon our previous work on run-time model checking of temporal correctness properties and automatic white-box testing using run-time assertion checking. This paper presents an architecture for the network embedded systems, a lightweight formal method that is based on formal statechart assertions for the design and development of networked embedded systems, and a process of using run-time monitoring and verification, in tandem with modeling and simulation, to study the timing requirements of complex systems early in the design process.
