Robust and Reliable Multicast Routing Protocol for IoT Enabled Vehicular Wireless Communications

Abstract

The recent studies shows that the multicast routing scheme satisfies the different Quality of Service (QoS) constraints which plays vital role in the IoT enabled applications. The present the multicast routing protocols focused on applications related to ad hoc sensor situations, consequently not powerful and solid enough for the IoT enabled smart traffic management networks like Vehicular Ad hoc Networks (VANETs). The efficient Intelligent traffic system (ITS) is core part of IoT enabled smart city project, hence designing efficient multicast routing protocol by considering the different types of applications (e.g. multimedia) is challenging research problem. The VANET routing is challenging due to the two key cases the scalability, mobility of vehicles, and density. The routing protocols of other wireless communications are not feasible to VANET dues to such challenges. To address the above challenges, we proposed Robust and Reliable Multicast Routing (R2MR). First we designed the simple but effective clustering protocol based on the key parameters such as mobility and geographical distance. The cluster head (CH) selection and formation performed according to probability of nodes using such parameters. After the cluster formation, we design the multicast routing protocol to establish the efficient communication path for Vehicle to Vehicle (V2V) or Vehicle to Infrastructure (V2I) communications. In this paper, to claim the robustness and reliability we designed the VANET networks small to large with sever mobility case and evaluate R2MR performance with state-of-art protocols.
