Modelling, Verification and Validation of the IEEE 802.15.4 for Wireless Networks

The purpose of this paper is to present a model of an mechanism Carrier Sense Multiple Access Collision Avoidance unslotted capable of accessing the environment. This mechanism is utilized in the latest IEEE 802.15.4 standard, which defines the wireless Medium Access Control and the Physical layerspecification for Low-Rate Wireless Personal Area Networks. For the model construction, Hierarchical Coloured Petri Nets will be used. Hierarchical Coloured Petri Nets are extensions of Coloured Petri Nets. Design/CPN tools will be used for simulations, and the model will be verified and validated by means of occurrence graphs generation.
