RA3D: Reputation-based Adaptive 3D Video Delivery in Heterogeneous Wireless Networks

Abstract

The continuous innovations in both high-end mobile devices and wireless communication technologies, fueled by the growing interest of mobile device users, have driven the latest development of mobile 3D video services. One of the critical challenges for mobile 3D video delivery is the limited bandwidth provided by the wireless communications between mobile devices. Nowadays, network operators are trying to cope with significant increase of data traffic amount and adopt diverse solutions to expand their network capacity. Among long-term solutions is network convergence, which involves close interworking of existing 2.5G/3G/4G networks with the new generation networks in terms of handover, network selection and network integration with other networks (e.g., WLAN, terrestrial microwave network, satellite network, etc.). In this context, the diversification in mobile devices and heterogeneity of the wireless environment make provision of always best connectivity of mobile users a challenge for the service providers. This paper proposes RA3D, a reputation-based adaptive 3D video delivery solution in heterogeneous wireless networks, which supports Always Best Experience to the mobile users by making use of multipath content delivery technologies.
