| Summary: | This paper presents an architecture for providing quality of service (QoS) and mobility-aware telescreen services in vehicular networks, named "in-vehicle telescreen" (IVT). Providing seamless imagery effect is a key challenge in the distribution of high-resolution and delay-sensitive infotainment IVT services under mobile and varying network conditions. In the IVT architecture, new functions of information and service quality management are introduced to manage the user registrations, service advertisements, network information, and service quality. We propose an adaptive selection of application QoS parameters and an IVT handover decision mechanism for providing seamless imagery effect and enhance user's multimedia perception. The proposed architecture can provide a sustainable channel rate based selection of content source, media resolution, and codec to improve the perceived visual quality. Furthermore, the paper presents a Link Expiration Time and Received Signal Strength Indicator based IVT handover decision mechanism that can minimize the number of handovers by selecting a stable path. An extensive simulation is performed to show the effectiveness of the proposed mechanisms. |
