The implementation of distributed real-time applications on wireless networks constitutes today a new important challenge and, in this context, the MAC protocols, which implement the frame exchange scheduling, have an essential role. This paper is precisely concerned by the specification of such MAC protocols. We specify MAC protocols called CANlike protocols because they are inspired by the MAC protocol of the network CAN which is a wired network. The presentation made in this paper, after a reminder of basic knowledges (wireless network physical layer, different topologies, CAN wired network, MAC protocol characteristics) shows how to integrate these basic knowledges in order to specify the CANlike protocols for several topologies (mono-hop topology and three different multi-hop topologies(chains)). In the conclusion too, we prove (by considering a mono-hop topology) the interest of the CANlike protocols for implementing applications in networked control systems (by comparison with the WiFi-DCF protocol).
