Power Efficient Transmission of Layered Video Through Wireless Relay Nodes

Efficacy of using a wireless relay node (WRN) to minimize total power dissipation in transmission of a layered video between two devices is presented. It is analytically shown that there is a feasible relay region that would have lower power consumption than direct transmission depending on both the encoding rate of each layer and received signal power level for provisioning required bit error rate.
