Data dissemination of application service by using member-centric routing protocol in a platoon of internet of vehicle (IoV)

In this paper, we proposed routing protocols for transmission over VANET in a platoon of vehicles that are driving together on the highway from the same starting point with the same route, and going to the same destination. The purpose of the routing protocols is to have cooperative video streaming service for a specific platoon member, i.e., it belongs to multiple-source to single-destination transmission. We considered two strategies that route data from multiple-source to single-destination. The first one is the severalty strategy in which each data source forwards packets through a route that contains common nodes of other paths as few as possible. The severalty strategy tries to increase the reliability of the route from source to destination and to achieve load balance by Helper-disjoint algorithm. The another strategy is the merged strategy which merges multiple traffic flows passing some specific nodes together. The main purpose of merged strategy tries to reduce the probability of collision while wireless resource are competing to forward data simultaneously and to increase the utilization of DSRC. In this paper, we proposed On-Demand Member-Centric Routing (OMR) protocol using the severalty strategy and Reactive Member-Centric Routing (RMCM) protocol using the merged strategy. Based on the simulation results, our proposed member-centric routing protocols effectively improve the packet delivery ratio and throughput compared with using others in the aforementioned platoon scenario over VANET.
