Abstract

Mobile devices have become important companions to most people, and are increasingly used for work and/or entertainment, most of the time consuming multimedia content. Diverse Quality of Service (QoS) metrics help estimate the enduser perceived quality or Quality of Experience (QoE) of the multimedia delivery to these mobile devices. However, energy consumption and device battery lifetime are also important parameters that severely impact end-user QoE. In this context, this paper proposes a QoE-aware Energy-saving Device-Oriented Adaptive Scheme (E2DOAS) for mobile multimedia delivery over wireless networks. E2DOAS is a solution which optimizes the trade-off between the end-user perceived quality of the multimedia delivery and the mobile device energy-saving. This trade-off is used in order to adapt the multimedia application delivery to the underlying wireless network conditions and multi-device characteristics. A crowdsourcing-based subjective video quality assessment was setup to model a non-reference perceptual video quality function. The performance of E2DOAS was evaluated against other adaptive schemes via network simulations in a wireless LAN single cell environment, in terms of energy savings, end-user perceived quality, average throughput, and packet loss.
