A Path Selection Scheme Considering Traffic Load for IEEE 802.16j Mobile Multi-Hop Relay Networks

We propose an effective path selection considering current traffic load for IEEE 802.16j MMR networks. Previous schemes either consider channel quality or the number of hops in choosing the effective path for traffic to MSs. Our scheme avoids crowded links even though they have high channel quality. Our scheme balances between the channel quality and the current traffic load, aiming at higher fairness of scheduling for the MSs. The simulation results show our scheme achieves higher throughput as well as fairness among MSs.
