Information distribution strategy optimization method based on dynamic feedback mechanism

Abstract

The invention discloses an information distribution strategy optimization method based on a dynamic feedback mechanism in Internet of Vehicles. The method comprises the following steps that S1, a system initializes an attribute set, a confidence set of a strategy maker group and a background probability vector of each attribute; S2, a strategy maker group generates an initial strategy, after the vehicle receives the message, whether the message is valid or not is fed back, and a road side unit collects attribute information and feedback data of the vehicle; S3, the road side unit deletes the abnormal feedback data; S4, an optimal strategy of the information distribution scene is determined according to a decision tree algorithm; S5, the road side unit updates the confidence set of the strategy maker group and the background probability vector of each attribute according to the optimal strategy; S6, the road side unit obtains the optimized information distribution strategy, encrypts themessage according to the optimized information distribution strategy, and broadcasts the encrypted ciphertext information to the vehicle. According to the optimization method provided by the invention, the information distribution strategy is effectively optimized by designing a dynamic feedback mechanism, and the information distribution accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an information distribution strategy optimization method based on a dynamic feedback mechanism in the Internet of Vehicles. Background technique [0002] In the Internet of Vehicles, policy makers send event information such as traffic accidents, traffic congestion, and traffic guidance to vehicles by formulating appropriate information distribution strategies, so as to achieve the purpose of real-time information release and real-time sharing, and effectively improve traffic operation service levels . Therefore, in the scenario of Internet of Vehicles information distribution, the information distribution strategy is particularly critical. [0003] In the Internet of Vehicles, information distribution in traffic services mainly adopts the form of broadcasting. Due to the open nature of the wireless network, the transmitted data is easily eavesdropped and tam...
