Schedulability Analysis of WSAN Applications: Outperformance of A Model Checking Approach (2205.10224v1)

Abstract: Wireless sensor and actuator networks (WSAN) are real-time systems which demand high degrees of reliability requirements. To ensure this level of reliability, different analysis approaches have been proposed for WSAN applications. Among different alternatives, analytical analysis and model checking are two common approaches which are widely used for the formal analysis of WSAN applications. Analytical approaches apply constraint satisfaction methods, whereas model checking generates explicit states of models and analyze them. In this paper, we compare the two approaches in schedulability analysis of WSAN applications using an application for monitoring and control of civil infrastructures, which is implemented on the Imote2 wireless sensor platform. We show how the highest possible data acquisition frequency for this application is computed while meeting the deadlines, and compare the results of the two approaches as well as their scalability, extensibility, and flexibility.
