Two-hop networks with energy harvesting: The (non-)impact of buffer size

Abstract: Abstract-In this paper, a two-hop channel is considered with energy harvesting transmitter nodes. In particular, the offline throughput maximization problem is solved for a constant power relay, and a relay with one energy arrival, in both cases assuming a finite buffer is available at the relay for temporarily storing data received from the source. The focus is on assessing the impact of this data buffer at the relay on optimal transmission policies. The solution is found indirectly, by first assuming that th… Show more

“…This way, the solution is computationally less expensive, but the feasible region is very limited. The online policy is found by iterating Equation 25 for each peak harvest rate for T 1,1 . As can be seen in Figure 8, the throughput curves achieved by the optimal offline policy and the online policy are monotonically increasing and concave in the peak harvest rate for node T 1,1 .…”
