摘要
针对车联网中节点自私行为对交通服务信息有效传输的影响,提出一种基于动态博弈演化模型的交通信息传输机制,通过对车辆网中的节点进行种群划分,分为3个群体,为不同种群设置不同的行为策略,通过多次博弈演化,使节点选择收益最大化的行为策略,有效抑制了自私节点的行为,激励节点选择合作行为。仿真结果表明,该方法能有效提高交通服务信息的传输效率,降低了节点自私行为对整个车联网中交通信息传输的影响。
To alleviate the impact of selfish nodes on forwarding transportation service information,a traffic information service transmission mechanism based on dynamic game evolution model was introduced.Nodes in vehicular networks were classified by three clusters.And each cluster had its own behavioral strategies set.Through processing of evolutionary games,the nodes in vehicular networks preferred to select the behavioral strategy which maximized the benefits to the nodes.This method can effectively restrain the behavior of selfish nodes,and encouraged nodes to select cooperative behaviors.The simulation results show that the method proposed can effectively improve the transmission efficiency of traffic information,and reduce the impact of selfish behavior of nodes on the whole network.
