Improving fairness in relay-based access networks

  title={Improving fairness in relay-based access networks},
  author={Lin Xiao and Laurie G. Cuthbert},
In this paper the fairness of the subchannel allocation problem for relay based OFDMA systems is studied. The proportional fairness algorithm is extended to a two-hop scenario to ensure that both direct-link users and relay-link users are fairly allocated capacity; this approach is called the "two-hop proportional fairness scheduling algorithm".
