  Abstract

In this article, we suggest optimizing packet length for two way relaying with energy harvesting. In the first transmission phase, two source nodes N₁ and N₂ are transmitting data to each others through a selected relay R. In the second phase, the selected relay will amplify the sum of the signals received signals from N₁ and N₂. The selected relay amplifies the received signals using the harvested energy from Radio Frequency (RF) signals transmitted by nodes N₁ and N₂. Finally, N₁ will remove, from the relay’s signal, its own signal to be able to decode the symbol of N₂. Similarly, N₂ will remove, from the relay’s signal, its own signal to be able to decode the symbol of N₁. We derive the outage probability, packet error probability and throughput at N₁ and N₂. We also optimize packet length to maximize the throughput at N₁ or N₂.
