A relay protocol in AF relaying wireless energy harvesting network

Abstract

In this article, we consider the energy harvesting system of wireless sensor networks with amplify and forward (AF) relay nodes. In this model, the working mode of the relay node is divided into two parts: first, the relay node collects the energy signal of the source node. Then, the data is sent to the target sensor through this energy. We put forward the relay cooperation protocol based on the relay forward protocol. We also calculate the mathematical expression of the interruption probability of the protocol and investigate the value of outage and throughout. Finally, the experimental simulation is carried out by MATLAB, the performance of relay cooperation protocol is better than that of relay protocol.
