Abstract

The invention discloses a software-defined heterogeneous Internet of Vehicles access management and optimization method, which comprises the following steps of: 1, designing an SDN-based vehicle communication network architecture to realize global management of a vehicle network; 2, setting a local database on a data plane, collecting vehicle information, and storing a management strategy issued by the control plane; 3, uploading the collected vehicle data to a control plane, and calculating vehicle network performance indexes on the control plane; and 4, determining the weight and benefit function of each performance index, finally determining the selection of an access network mode through adopting an evolutionary game method, and issuing the access network mode to a vehicle of the dataplane. According to the software-defined heterogeneous Internet of Vehicles access management and optimization method, the vehicle access mode is flexibly selected based on different service requirements, so that the network service quality of the vehicle heterogeneous network is optimized according to the requirements of the required service, the network performance is greatly improved, and the service quality of the vehicle communication network is improved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and relates to an SDN-based heterogeneous Internet of Vehicles access management control and access network optimization method. Background technique [0002] As a key technology in intelligent transportation systems (ITS), vehicle ad hoc networks (VANETs) can connect vehicles in roads and urban areas and provide wireless communication between vehicles and between vehicles and roadside infrastructure. Utilizing VANETs communication technology and vehicle perception capabilities, it can be applied to some advanced applications. For example, VANETs can support a variety of vehicle services, such as vehicle information exchange (such as speed, acceleration, and location), safety services (including cooperative collision warning, cross- Collision avoidance and remote vehicle diagnosis) and entertainment services (such as online video, online games, online upload and download), etc. ...
