By taking advantage of the ever growingdeployment of wireless networks, the automotiveindustry is increasingly enabling vehicles to communicatewith one another and with the infrastructure,with benefits to information delivery and safety onthe road. Vertical Handovers can be used to ensurethat the Quality of Service demanded by applications(e.g., throughput, latency) is met while the vehicleis changing its position. In this paper we present aVertical Handover Decision Algorithm empowered bythe IEEE 802.21 standard and its services. Our proposedalgorithm uses the vehicle’s on-board unit featuresand considers the geolocation, the car navigationand a realistic propagation model for heterogeneousunderlying networks such as Wi-Fi, WiMAX,and UMTS. Our results demonstrate, through a caseof study, that QoS can be guaranteed when locationand networking parameters are jointly consideredwhen performing vertical handover.
