摘要:
因为车辆节点的移动方向与速度大小均存在差异,节点间通信链路的持续时间短暂,通信质量难以满足车载自组织网络(VANET)中传递消息的要求.利用成簇算法来提高通信链路的稳定性是解决上述问题的有效途径,但目前成簇算法的设计主要针对高速公路环境,没有考虑车辆节点方向、速度变化频繁的城市环境.在经典成簇算法的基础上提出了一种更加稳定且可靠的VANET成簇算法.该算法针对城市环境对成簇算法的多个稳定性条件进行改进,同时考虑信道质量对通信服务质量的影响.最后利用SUMO仿真平台模拟真实的城市交通环境,并通过NS-2仿真平台验证该算法的各项指标.仿真结果表明,对比LID算法和MOBIC算法,提出的算法具有更高的稳定性和可靠性,且端到端的数据传输时延更低.
Abstract:
Due to the differences in the moving direction and speed of vehicle nodes,the duration of communication link between nodes isshort,and the communication quality is difficult to meet the requirements of message delivery in vehicular ad hoc network (VANET).To improve the stability of communication link with clustering algorithm is an effective way to solve the above problems,but the currentdesign of clustering algorithm is mainly aimed at the expressway environment,not taking into account the urban environment with direc-tion of vehicle nodes,speed changes frequently. Based on the classical clustering algorithm,we propose a more stable and reliable VA-NET clustering algorithm which improves several stability conditions of clustering algorithm for the urban environment and considers theinfluence of channel quality on communication service quality. Finally,SUMO simulation platform is used to simulate the real urban traf-fic environment,and NS-2 simulation platform to verify the indexes of the algorithm,which shows that the proposed algorithm has higherstability and reliability and lower end-to-end data transmission delay compared with LID algorithm and MOBIC algorithm.
