  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.
