Abstract :
In this paper, we study a relaying network employing a rateless coding scheme proposed in the literature. We consider the problem of an energy-efficient operation of the scheme and derive algorithms that maximize the achievable rate for specified energy-per-bit bounds at the relay nodes. For this, we identify the rate function as a standard interference function, which allows to design efficient algorithmic solutions for solving the problem.
