A QoE aware Clustering MAC protocol for Internet of Vehicles (QoEC-MAC)

An Internet of Vehicles (IoV) network is an evolution of Internet of Things (IoT) and VANET. In IoV, the Medium Access Control (MAC) protocol based on the standard 802.11p remains a big challenge for broadcasting safety messages. As the number of users increases, attention is given to Quality of Experience (QoE) and channel allocation. This paper proposes an efficient QoEC-based MAC scheme for IoV. The goal of this paper is to increase the network's effectiveness and the quality of service it offers. In our scheme, vehicles are organized into clusters. The cluster head is responsible for attributing slots, forwarding messages sent by their cluster members, and scheduling inter-cluster and intra-cluster communications. The efficiency of the QoEC-MAC scheme is evaluated with several simulations. The simulation results show that the proposed QoEC-MAC protocol achieves a lower collision ratio, higher throughput, and shorter delay.
