Relay Selection in Energy-Harvesting Systems with Packet Storage and Finite Battery

Abstract

In this thesis we study the relay selection problem for a buffer-aided and energy harvesting cooperative system A number of relays harvest energy from the source signal and one relay are selected to forward the source signal using the harvested energy Since the harvested energy is often weak the best practice is to accumulate the harvested energy by storing it into the rechargeable battery With the aid of energy and data storage both limited in size an important question is how to determine the action of each relay namely receiving data or forwarding the source signal A relay selection scheme called dual buffer relay selection (DBRS) is proposed considering the data buffer energy buffer and channel status simultaneously To evaluate the performance of DBRS theoretical analysis based on Markov chain model is performed Simulation results are presented to validate the analysis accuracy and get insights into the system performance subject to numerous key parameters
