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.
