Perceived Quality Model for Supporting Full Session Mobility in Multimedia Service Delivery Process

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 215)

Abstract

Context-awareness has empowered advanced multimedia computing technology to provide user-oriented services and environment. This research aims at achieving a seamless video delivery service concentrating on the user’s mobility patterns during a multimedia streaming service session. Mobility supporting technology providing seamless services are categorized into host mobility and user mobility. The former corresponds to host-level handoff while the latter refers to user-level handoff. In host-level handoff, the influential parameters affecting the quality of video consumption are the total distance between the hosts, the distance for streaming to resume while user is in mobility mode and the screen size of the end host. The interdependency amongst the parameters is evaluated by a user subjective assessment and a befitting video quality model is developed, accordingly. Additionally, the optimal video delivery switching point to enable user mobility based video service is studied based on a quality analysis of host mobility services at varying distances among hosts. This quality model supporting a complete mobilization has a high correlation with the assessed quality and enables an adequate seamless mobility for multimedia service delivery.
