Resource allocation issue in uplink OFDMA multi-hop relay networks was investigated.Firstly,with constraints such as maximum transmission power being imposed,a multi-cell optimization model for resource allocation in uplink OFDMA multi-hop relay networks was formulated.By applying RAW CACAO NIBS non-cooperative game and pricing theories,the optimization is transformed into the case where power was independently allocated on each sub-channel.The existence and uniqueness of Nash equilibrium for power allocation model which was based on non-cooperative was proven,and accordingly a distributed algorithm was proposed.

Simulation results show that,the proposed algorithm can improve COOK BOOK the system throughput effectively while profoundly reducing total system transmission power,thus achieving much higher energy efficiency ratio.
