Abstract

Summary: The Internet of Vehicle (IoV) is known as a kind of highly dynamic network, in which the vehicle needs to exchange information with the fixed Roadside Unit (RSU) or other moving vehicles frequently. In order to improve the performance of existing RSU access schemes, in this paper, we proposed a BUS‐aided RSU connection scheme based on the software‐defined networking (SDN) and evolutionary game theory, in which the costs during multiple‐user access and following RSU handoff are considered. At first, we constructed a SDN‐IoV architecture and showed the benefits by introducing SDN into IoV. After that, we modified the original OpenFlow protocol stack in order to apply it to the wireless vehicular networks. Next, to explore more accessing opportunities in moving cases, the BUS was further introduced as a mobile RSU. With these fixed and mobile RSUs, an evolutionary game is then envisioned to model the multiple‐user access process with the aim to maximize the rewards of all participants. To make our proposed protocol practical, we also illustrated the implementation procedure of our protocol on the OPNET platform and gave out the finite state machine (FSM) of major routines. Numerical results showed that our proposed scheme could outperform the schemes without BUS, SDN, and game theory enabled, in terms of RSU load ratio, throughput, and handoff times. Abstract : We investigated the RSU access problem within multiple vehicle nodes, with the help of SDN architecture and evolutional game theory. The network performance can be benefited by the "GOD view" from SDN controller and the optimization from the iterations in evolutional game. We also demonstrated the feasibility to incorporate the OpenFlow protocol into the wireless world, with few modifications and forward compatibility to the original protocol stack.
