In this paper, we propose a new cooperative wireless transmission in a scenario where the
source salvages the energy during the relay's transmission considering the fact that the
source does not need to retrieve the transmitted message. We also evaluate a direct
wireless transmission with wireless energy transfer as a reference. We analyze the
performance of these transmission techniques in terms of outage probability. Our analytical
results reveal the advantage of energy salvage in combination with spatial diversity over the …

This paper addresses the problem of throughput maximization in an energy-harvesting two-
hop amplify-and-forward relay network. We obtain optimal policies for transmission power
for two cases. First, we assume non-causal knowledge of the harvested energy and that of
the fading channel states. Then, we assume that this information is known only causally. We
propose an effective algorithm to solve the power-use problem in the non-causal (offline)
case. For the causal (online) case, we cast the problem as a Markov decision process (MDP) …
