Embodiment Construction

[0081] Embodiments of the present invention are described in detail below in conjunction with technical solutions and accompanying drawings;

[0082] In order to study the dynamic evolution process of RSU access and the impact of ESS on network performance, we set the parameters as follows: φ=0.1, β=0.15, δ=0.1, γ=2, S / N=30dB, R=1000; we mainly The RSU selection problem based on evolutionary game is studied through the following three aspects: the stability of ESS, the convergence of ESS, and the influence of ESS on network performance;

[0083] In VANET, since the movement of vehicle nodes is often affected by various factors such as roads, adjacent vehicles, and traffic signals, this paper uses the Vanet MobiSim simulation tool to simulate the vehicle driving mode, and adds the traffic signal mechanism. map to construct a realistic simulation scene; such as Figure 4 , set the size of the simulation scene area to 2.0km*2.0km; set the communication range of the RSU to 1000m;...

Abstract

The invention belongs to the technical field of mobile communication and discloses an evolutionary game method for solving the access problem of an RSU in a VANET. Firstly, the research problem of how to select access to the RSU so as to ensure that a vehicle can obtain a high-Qos service when the vehicle moving at a high speed is in a confined communication range of the RSU is determined. Secondly, the research process of considering the characteristics, for example, the network topology of the VANET frequently varies, the RSU is not evenly distributed, the RSU is confined in the communication range, and the number of vehicles in an RSU covering range is large is determined. The evolutionary game method solves the problems caused by unordered competition on RSU bandwidth resources of vehicles in a special net theory environment of the VANET. The evolutionary game method for solving the access problem of the RSU in the VANET has the advantages that the proper RSU is selected according to the provided evolutionary game method, and high efficiency of requesting services by the vehicles under the situation that the topology of the VANET varies frequently is ensured.

Description

technical field [0001] The invention belongs to the technical field of mobile communication; when a fast-moving vehicle in VANET (vehicle Ad Hoc Network, Internet of Vehicles) passes through an RSU (RoadSide Unit, Roadside Unit) with limited coverage, it solves the request of the vehicle to the RSU according to the evolutionary game model QoS (Quality of Service, service quality) inefficiency in service; Background technique [0002] When a vehicle passes through an RSU in VANET, it first requests services by accessing the RSU, and there are two main problems when the vehicle accesses the RSU: [0003] Problem 1: Due to the high-speed mobility of the vehicle, it is difficult to maintain the end-to-end connection between the vehicle and the RSU; [0004] Problem 2: Limited bandwidth and channel resources cause vehicles to compete for RSU bandwidth resources in disorder; when a vehicle is in the overlapping coverage area of ​​multiple RSUs, there is a problem that the vehicle...
