Problems solved by technology

[0006] Existing research on VANET routing selection algorithms mainly considers routing selection based on factors such as node communication distance, link duration, and link communication probability. There are many factors such as mobility and transmission characteristics. In addition, when optimizing the selection of cooperative relays, usually only the performance optimization of SVs is considered, and factors such as the transmission requirements of RVs, steady-state transmission characteristics, and the benefits of providing relay forwarding services are not fully considered. , may lead to RV communication performance cannot be guaranteed and the overall network performance is severely limited

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] In the present invention, M source vehicles (SV) that intend to communicate are involved in forwarding information to a destination vehicle through a relay vehicle (RV). One-hop routing is performed on all SVs at the Routing Management Center (RMC), and this selection strategy can be extended to multi-hop routing scenarios.

[0027] In the application scenario of the present invention, the source vehicles SV1 and SV2 respectively transmit data to the respective destination vehicles DV1 and DV2 via the relay vehicle. The present invention can be applied to the scenario where multiple SVs perform data forwarding.

[0028] figure 1 For the VANET routing selection system model in the present invention, assuming that the numbers of SVs and RVs are M and N r...

Abstract

The invention discloses a vehicular ad hoc network route selection method based on a game theory, and relates to the technical field of communication. The method comprises the steps that a source vehicle to be in communication detects whether a communication destination node is a single hop neighbor node of the communication destination node or not, if yes, a data package is sent, and otherwise a route requesting message is sent to a route management center; the route management center determines a candidate relay vehicle of an SV, an SV route selection problem is modeled to be a game model, the gain and loss function of the SV and an RV is modeled, and an SV optimization route selection scheme can be determined by solving a game model optimization solution. According to the vehicular ad hoc network route selection method based on the game theory, the various factors affecting the route transmission characteristic are comprehensively estimated, based on combination optimization of the optimized SV and RV gains, the best route selection of the SV is achieved, the QoS of a user can be effectively guaranteed, and combination property optimization of the system is achieved.

Description

technical field [0001] The invention relates to the field of wireless communication, especially the routing selection technology of vehicle ad hoc network (VANET). Background technique [0002] With the rapid development of mobile communication and network technology, Vehicle Ad-hoc NETwork (VANET), as an important part of Intelligent Transportation System (ITS), has received extensive attention in recent years. VANET is a self-organizing, open-structure inter-vehicle communication network that provides communication between vehicles and between vehicles and roadside infrastructure. VANET combines Global Positioning System (GPS) and wireless communication technologies, such as wireless local area network (WLAN), cellular network, etc., to provide high-speed data access services for vehicles in high-speed movement, and to support information interaction between vehicles. It has become an effective technology to ensure the safety of vehicles, provide high-speed data communica...
