Abstract :
We consider energy-efficient resource allocation for wireless fading channels. We study the case where a sliding window ARQ protocol such as Go-Back-N is used to provide reliable communication. In particular, we consider power allocation policies that take into account the underlying window dynamics. An optimal dynamic programming approach and a sub-optimal approach based on renewal theory are given. Numerical results comparing these approaches are also presented.
