WebApr 10, 2024 · The cluster size l is relative to the number of alive nodes in the network. After the cluster formation process is completed, the CH notifies the base station about the cluster members. The CH then forwards a TDMA schedule to its relevant cluster members, along with its id. The cluster members initiate the communication process with their CH ... WebFeb 23, 2014 · Recently a novel multi-channel MAC protocol called TDMA cluster-based MAC (TC-MAC) for Vehicular Ad hoc NETworks has been proposed by Almalag and al. [15]. It is based on stable clusters heads which are in charge of TDMA time slot assignment. TC-MAC provides an efficient time slots utilization for the exact number of active vehicles.
