QoS optimized and energy efficient power control for deep space multimedia communications in InterPlaNetary networks

摘要

In this paper, we propose a QoS optimized power control approach to achieve an optimum multimedia communication quality over the InterPlaNetary (IPN) Internet with a strict energy consumption budget. The transmission power to send each frame is optimized by jointly considering the unequal distortion reduction gain of the multimedia data, energy consumption budget, and overall multimedia communication quality. Simulation results show that the proposed Unequal Error Protection (UEP) adaptive power control approach improves multimedia data transmission quality and achieves the energy utilization efficiency in energy-constrained IPNs.
