New Method of Vehicle Cooperative Communication Based on Fuzzy Logic and Signal Game Strategy

With the rapid development of the Internet of Vehicles, at the same time, due to the limited storage space of vehicles and more and more data requirements, vehicles need more and more vehicle-to-vehicle collaboration. At this time, a vehicular ad-hoc network (VANET) is required for inter-vehicle communication cooperation, and link breaks often occur due to the rapid movement of vehicles and the uncertainty of vehicle communication quality, which affects communication quality. Because of these situations, this paper proposes a vehicle cooperative communication method based on fuzzy logic and signal game strategy, obtains more real vehicle position and speed information on the Kalman filter, and then selects relay nodes to assist in requesting information message distribution of fuzzy logic. Each time the vehicle receives a request, the first data information is returned to the signal game. If all the information requests are not received the first time, the information requesting vehicle will send the second information request according to the signal strength and the beliefs observed on the previous vehicle. The experimental verification shows that this method can realize the function of vehicle cooperative communication, solve the problems of low VANET link stability and broadcast storm, and has a good supporting role in establishing the practicality of vehicle cooperation in VANET.
