Abstract :
In this paper, we study the issue of optimizing transmission power (energy per symbol) for minimizing the expected energy required to deliver a frame to the destination node in a point-to-point link employing an automatic repeat request (ARQ) scheme over a fading channel. We derive the expected energy as a function of the transmission power and derive a simple optimization algorithm based on the properties of this function.
