Information acquisition, calculation and transmission architecture based on fog computing

Abstract

The invention discloses an information acquisition, calculation and transmission architecture based on fog computing, which is applied to an Internet of Vehicles system. The architecture at least comprises a request terminal, a sending terminal, a fog node and a cloud node, wherein the fog node and the cloud node are used for information calculation and transmission. The method comprises the following steps: 1, vehicle information collection: enabling all vehicles periodically to send own information to surrounding vehicles and fog nodes where the vehicles are located to form a vehicle topological graph; 2, requesting service by the vehicle A: selecting a vehicle B which wants to obtain information by the vehicle A, and sending the request information to the vehicle B under the assistanceof a fog node; 3, after the vehicle B parses the request, if the vehicle B agrees to share the information, enabling the vehicle B to send the information to the vehicle A under the assistance of thefog node; and 4, information transmission routing: enabling the cloud node to assist the fog node to select an optimal transmission path. The invention provides a scheme of cooperative driving betweenvehicles, and a fog node assisted calculation and transmission method is adopted to realize rapid information interaction between vehicles.

Description

technical field [0001] The present invention relates to Internet of Vehicles, fog computing, SDN and intelligent transportation systems, in particular to a fog computing-based information collection, calculation, transmission framework and its processing method. Background technique [0002] At present, the communication between vehicles is mainly based on two methods: one is based on the cellular network, the vehicle accesses the Internet through the cellular network, and performs data transmission through the uplink and downlink of the cellular network. With the rise of 5G, the seamless coverage of the cellular network provides high reliability and real-time information transmission between vehicles. The other is based on short-range wireless network communication technology, and communicates between vehicles or between vehicles and infrastructure (DSRC equipment) through DSRC equipment such as RSU and OBU. Through DSRC equipment, vehicles can still exchange information i...
