Abstract

In wireless networks, management of harvested energy is important due to limited and stochastic energy sources. In this paper, throughput maximization for energy harvesting two-hop communication with half-duplex relays is considered. Optimal transmission policies are found for one relay and two parallel relays under the assumption of known energy arrivals at the source and the relays. For each case, a convex optimization problem is formulated to efficiently solve and identify properties of the optimal transmission policies. Performance comparisons are provided to investigate the impact of multiple relays and energy harvesting.
