QoE and QoS-aware Handover for Video Transmission in Heterogeneous Vehicular Networks
Handover, QoE, VANET, multimedia
Vehicle Ad Hoc Networks (VANETs) offer a wide range of multimedia services ranging from safety and traffic warnings to entertainment and advertising videos. In this context, users can access content through vehicle-to-infrastructure (V2I) communication, which may consider different wireless networks, such as, LTE, Wi-Fi, etc. However, real-time video streaming at a VANET with Quality of Experience (QoE) and Quality of Service (QoS) is a challenging task, due to the high vehicles mobility that causes communication failure with the infrastructure. This master dissertation introduces a QoE- and QoS-aware handover algorithm for heterogeneous VANETs. The proposed algorithm considers the Analytic Hierarchy Process (AHP) to choose the base station that the vehicle must connect based on multiple criteria, namely, signal strength, QoE, QoS.
