Abstract

In this paper we report on modelling and verification of a medium access control protocol for wireless sensor networks, the LMAC protocol. Our approach is to systematically investigate all possible connected topologies consisting of four and of five nodes. The analysis is performed by timed automaton model checking using Uppaal. The property of main interest is detecting and resolving collision. Evaluation of this property for all connected topologies requires more than 8000 model checking runs. Increasing the number of nodes would not only lead increase the state space, but to a greater extent cause an instance explosion problem. Despite the small number of nodes this approach gave valuable insight in the protocol and the scenarios that lead to collisions not detected by the protocol, and it increased the confidence in the adequacy of the protocol.
