An 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 the Internet of Vehicles, comprising the following steps: S1. System initialization attribute set, confidence set of policy maker group and background probability vector of each attribute; S2. Strategy The group of planners generates an initial strategy. After the vehicle receives the message, whether the feedback message is valid or not, the roadside unit collects the vehicle's own attribute information and feedback data; S3. The roadside unit deletes the abnormal feedback data; S4. Determines according to the decision tree algorithm The optimal strategy for the information distribution scenario; S5. The roadside unit updates the confidence set of the policy maker group and the background probability vector of each attribute according to the optimal strategy; S6. The roadside unit obtains the optimized information distribution strategy, and based on this Encrypt the message and broadcast the encrypted ciphertext information to the vehicle. The optimization method of the present invention effectively optimizes the information distribution strategy by designing a dynamic feedback mechanism, and improves the accuracy of information distribution.

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...

Problems solved by technology

However, the policy makers themselves have limited perception ability, sometimes unintentionally or even deliberately formulate wrong distribution strategies, thus affecting the quality of information services
