Wireless mesh network (WMN) is an innovative approach in packet radio networks. Routing is one of key challenging issues since the unpredictable behaviours of the medium and the network topology. In this paper two statistical MAC layer parameters are explored: available residual bandwidth and Frame Transmission Efficiency (FTE). A metric called Degree of Congestion Control is defined so that the routing algorithm can effectively search the better quality path with least congestion towards the final destination. A novel routing protocol called Least Congestion QoS-aware Routing (LCQSR) using cross-layer design approach is proposed to achieve a good trade-off between QoS aware and network performance based on DSR. The simulation results show that the protocol can improve the performance of network congestion effectively in terms of delay, packet delivery ratio and throughput.
Researchers in REF proposes a novel congestion control routing algorithm named Least Congestion QoS-aware Routing (LCQSR).
