Embodiment Construction

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] In this embodiment, it is specifically described by taking N relay vehicles (RVs) and M source vehicles (SVs) that need to forward information through the RVs, and performing unified relay allocation for all SVs at the AP as an example.

[0026] figure 1 It is an application scene diagram of the present invention, and the present invention can be applied to the scene where the SV cannot directly communicate with the AP and needs to perform relay forwarding.

[0027] figure 2 For the system model of the present invention, it is assumed that there are multiple SVs and RVs, and each RV can be virtualized into multiple VRVs. Each SV can only select at most one VRV to forward data for it, and each VRV can only select at most one SV to forward its data.

Abstract

The invention relates to a VANET (Vehicular Ad-Hoc Network) relay vehicle selecting method, and belongs to the technical field of wireless communication. Aimed at the problem that RVs (Relay Vehicles) are required to be selected from multiple SVs (Source Vehicles) in a VANET, the method virtualizes each RV into multiple VRVs (Virtual Relay Vehicles) based on the NFV (Network Function Virtualization) technology, further models an SV traffic arrival curve and an RV service curve by adopting the theory of network calculus, assesses the transmission performance of SV service passing through each VRV, and selects the VRV with optimal transmission performance based on a SV QoS (Quality of Service) demand, thereby realizing RV optimization selection. The method can realize system overall performance optimization and obtain an optimal RV selection scheme, thereby having a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for selecting a relay vehicle in a vehicle ad hoc network. Background technique [0002] Vehicle Ad-hoc Network (VANET) is a self-organizing, open-structure inter-vehicle communication network that can provide 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 vehicle driving safety and provide high-speed data communication, intelligent traffic management and in-vehicle entertainment. [0003] In VANET, some vehicles cannot communicate directly with the AP due to factors such as the rapid move...
