Analytically evaluating the impact of wireless channel behavior on an energy-efficient rate-controlled video transmission system

The challenging goal for the scientific community in the next future is to provide energy-efficiency for telecommunications networks. However, making a network device green can cause performance deterioration. Extending a previous work, in this paper we propose a cross-layer approach for the energy-efficient transmission of multiplexed rate-controlled multimedia streams over wireless channels. In particular, we have introduce an Energy-Efficient ARQ protocol, which is able to exploit the wireless channel correlation. Moreover, using an analytical model of the system, we present a deep analysis on the impact of the wireless channel behavior on the performance of the proposed scheme.
