[Abstract]:Van net, Vehicular Ad Hoc Network) supports network access, video stream and content distribution, provides real-time news / entertainment and other multimedia resources for vehicle users, and brings great benefits to people's daily life. Due to the installation of wireless communication equipment in the vehicle interior and on the roadside infrastructure (RSUU, Road-Side Unit) in VANET, vehicles can obtain multimedia files by means of vehicle-to-vehicle communication (V2V), Vehicular to Vehicular) and vehicle-roadside infrastructure communication (V2R, Vehicular to RSU). However, in V2V communication, the instability of communication link and the selfish behavior of rational vehicle may lead to the failure of multimedia resource query and cooperative transmission. In V2R communication, malicious vehicle sends spam to RSU, blocks legitimate vehicle and RSU communication, causes legal vehicle access failure and cannot obtain multimedia source file, and malicious vehicle steals and forges V2R communication content. Makes it impossible for a legitimate vehicle to obtain a complete multimedia packet. Among the many technologies involved in VANET, multimedia data sharing is one of the most difficult problems in VANET. Therefore, aiming at the problem of multimedia cooperation and sharing in VANET, this paper mainly studies the following two aspects: Firstly, aiming at the problem of resource query and transmission failure caused by broken chain and selfishness of vehicle in V2V communication in multimedia cooperative sharing, a multimedia cooperative sharing mechanism based on P2P-BT is proposed in this paper. Because of the irregular high speed movement and irregular topology change of vehicle in VANET, it is difficult to implement the traditional static P2P-BT scheme in VANET. Therefore, combining the characteristics and track of the vehicle in VANET, this paper establishes the VANET hierarchy architecture. On this basis, this paper proposes a multimedia file query mechanism based on Tracker and a tree return mechanism based on indirect reciprocal game, in which indirect reciprocal game is used to encourage vehicle cooperative sharing. The efficiency of V2V communication transfer resource is improved. Secondly, aiming at the problem of RSU secure access and communication for vehicles with multiple RSU overlapped coverage in V2R communication in multimedia cooperative sharing, a Steinberg game model is proposed in this paper, in which Visual Cryptography is incorporated into the game. The game model not only satisfies RSU's pursuit of benefits, but also maximizes the utility of vehicle users. Visual Cryptography method effectively prevents the malicious vehicles in VANET from attacking RSU, intercepts and forges the content of V2R communication, and reduces the communication delay. Improved RSU resource utilization and message integrity. It makes the vehicle access RSUs successfully, and can download resources from RSU smoothly, and improve the satisfaction of vehicle users. At present, the research of P2P network and VANET are two hot spots in the field of distributed computing and mobile communication network. The research in this paper provides some suggestions and technical support for the future research work of P2P and VANET, which has important practical significance and research value.
