Query: Two-hop Communication with Energy Harvesting   Communication nodes with the ability to harvest energy from the environment
have the potential to operate beyond the timeframe limited by the finite
capacity of their batteries; and accordingly, to extend the overall network
lifetime. However, the optimization of the communication system in the presence
of energy harvesting devices requires a new paradigm in terms of power
allocation since the energy becomes available over time. In this paper, we
consider the problem of two-hop relaying in the presence of energy harvesting
nodes. We identify the optimal offline transmission scheme for energy
harvesting source and relay when the relay operates in the full-duplex mode. In
the case of a half-duplex relay, we provide the optimal transmission scheme
when the source has a single energy packet.
