位置感知及背景扫描下软件定义车联网无缝切换方案
Seamless Handover Scheme for Software-Defined Internet of Vehicles With Location Awareness and Background Scanning
摘要
Abstract
To address the signaling redundancy in centralized schemes and the IP reconfiguration bottleneck in distributed schemes within traditional architectures of the internet of vehicles,a seamless handover scheme for software-defined internet of vehicles is proposed,which integrates location awareness,multi-interface back-ground scanning,and dynamic flow table redirection techniques.First,the shortcomings of traditional central-ized architectures are analyzed,along with the factors contributing to excessive handover delay.Then,relying on the dynamic scheduling capability of the global network view of the software-defined network(SDN)con-troller,the target base station selection efficiency is optimized through predictive scanning.Finally,consider-ing the characteristics of vehicle multi-network interfaces,data transmission and background scanning tasks are decoupled,and multi-link load balancing is utilized to achieve uninterrupted service migration.Experimental results demonstrate that the proposed scheme can effectively reduce the handover delay while ensuring the quality of service(QoS)requirements of vehicular applications.关键词
