Adaptive RF Energy Harvesting Relaying Protocol for Bidirectional Multi-Relay Multi-antenna Cooperative Network over Nakagami Fading

In this paper, we have explored the performance of a bidirectional amplify and forward energy harvesting half-duplex multi-relay multi-antenna network system over the Nakagami fading channel. We have proposed the delay limited and delay tolerant transmission modes when simultaneous transfer of energy and information occurs between terminal nodes via a cluster of relay nodes. Mathematical expressions of the outage probability, achievable throughput and the ergodic capacity are proposed, analyzed and illustrated using Monte Carlo simulation. The research result shows the advantage of using multiple antennas in the relay node.
