Abstract

A power allocation scheme is proposed to improve the outage performance for a wireless cooperative network with multiple energy-harvesting relay nodes. The optimization problem is formulated to minimize the system outage probability under the constraints of both relay joint maximum transmit power and individual energy limitation caused by energy-harvesting. The optimal transmit power of multi-relay can be solved by using Lagrange multiplier method. Simulation results show that the proposed power allocation scheme can reduce system outage probability efficiently.
