State of the Art, Reliable, and Trusted Communication in Vehicle to Everything (V2X) Networks

Transportation systems are a necessity of modern life. To achieve safe and fast transportation, the intelligent transportation system is being developed. In this system, the main base station facilitates communication between vehicles and all other roadside entities using vehicle to everything networks. Various technologies have been built to support this communication. After receiving the information, vehicles can make their own decisions. This data communication is done in real time. But, if any of these data packets are dropped, the vehicle will make inaccurate decisions, so we need to have reliable data communication. All data communication will be accomplished through a system of neighboring nodes. There may be some malfunctioning nodes that lose packets in between, so a trusted and reliable link is necessary for efficient and secure data communication among the nodes. This paper presents a survey of various algorithms designed for the reliable delivery of data packets, algorithms for secure data transfer, and various types of attacks. After that, various schemes for building trust in parties sending data packets if also presented for survey.
