Abstract

Energy harvesting (EH) is an attractive solution to prolong the lifetime of wireless devices As the replacement of traditional battery-powered relay nodes EH relays extract energy from the signal of the source node and use the harvested energy to perform information relaying enabling a self-sustainable cooperative network To use the harvested energy efficiently which is limited due to the energy loss by wireless channel impairment and RF-DC conversion it is important to properly schedule the two tasks for relays namely information and EH within a transmission block In this thesis we investigate block scheduling and relay selection problems in a cooperative networks with EH relays In terms of block scheduling we consider two variants of time division multiplexing including partial time reuse and full-duplex scheduling In terms of relay selection we propose a relay selection scheme where selected max-max relay selection (S-MMRS) considers both the source-relay channel for EH and the relay-destination channel for information relaying in selecting the cooperating relay To evaluate the performance of the proposed S-MMRS we theoretically analyze the outage probability and the throughput and the simulation results are presented to verify the analysis accuracy and demonstrate the impact of system parameters to the proposed relay selection scheme
