A QoS-based Opportunistic Routing Mechanism in Social Internet of Vehicle

With the development of Internet of Vehicles, vehicles establish the social relationships with other vehicles and road side units for exchanging information, which is called Social Internet of Vehicles (SIoV). Making use of the relationships, we propose a QoS-based opportunistic routing mechanism to guarantee the QoS requirement and route reliable of information transmission in this paper. First, we establish a mathematical model for QoS evaluation considering the transmission correct ratio and delay, which can accurately estimate the QoS of road section. Then, we propose the QoS-based opportunistic routing mechanism, which aims to form a reliable and robust route path. Finally, the obtained simulation results validate the accuracy and correctness of our approach.
