Relay Selection In Wireless Information And Power Transfer Multi-relay Networks With Energy Causality

5979,5977,5978

Energy Harvesting (EH) and simultaneous wireless information and power transfer (SWIPT) is promising solution for energy constrained network. In this paper, we purpose multi-relay selection (MRS) algorithm and adopt relay ordering criterion based on maximum harvested power to improve the performance and life time of battery dependent nodes . We adopt amplify and forward (AF) based relaying strategy
for optimum relay selection subset N from available M relays. Simulation and numerical results demonstrate that our purposed scheme is optimum in terms of energy efficiency and system outage probability.
