The Vehicular Ad hoc NETworks (VANETs) are of high mobile and dynamic in nature. They are highly prone to network discontinuity, thereby the applications running on the vehicles get degraded in its service. The network selection for VANETs is done based on network attributes and user Quality of Service (QoS) demands. In this work, a two-phase access network selection scheme is proposed for VANETs. In the first phase, the available networks are ranked based on QoS demands using Weighted Sum Method (WSM). During the second phase, based on availability of resources, handoff decision and access network selection are carried out using game theory approach. Here, the vehicle and network play the game by adopting different strategies, thereby the optimum Nash Equilibrium (NE) is obtained. The simulation results validate that the proposed scheme outperforms the conventional Multiple Attribute Decision Making (MADM) schemes.

基于加权和和博弈论方法的车载自组织网络两阶段接入网络选择方案

车载自组织网络 (VANET) 本质上具有高移动性和动态性。它们很容易出现网络中断，因此在车辆上运行的应用程序的服务质量会下降。VANET 的网络选择是基于网络属性和用户服务质量 (QoS) 需求完成的。在这项工作中，提出了一种用于 VANET 的两阶段接入网络选择方案。在第一阶段，可用网络使用加权和法 (WSM) 根据 QoS 需求进行排名。在第二阶段，基于资源的可用性，使用博弈论方法进行切换决策和接入网络选择。在这里，车辆和网络采用不同的策略进行博弈，从而获得最优纳什均衡（NE）。
