Book Chapter Description

There has been a rapid growth in the need to support mobile nodes in Wireless Sensor Networks (WSNs). This may lead to several uncertainties and stochastic events such as messages loss, collisions on medium and even loss of nodes. Therefore, it is essential to ensure the efficiency of mobility based wireless sensor protocols. A lot of protocols have been proposed to consider mobility in the MAC layer as well as in the network layer. We opt to study formally one of these protocols using Statistical Model Checking (SMC). The chosen protocol is CFMA (Collision Free Mobility Adaptive) MAC protocol, for WSNs. This protocol performs well in both static and mobile scenarios. In this paper, we make a formal study for its principal algorithms by modeling, first, its work-flow using probabilistic timed automata. This stochastic formalism leads to consider several random events with more realism. Furthermore, a performance analysis is performed by verifying the qualitative and quantitative properties of this protocol using UPPAAL SMC tool [6].
