Abstract：In order to improve the capacity of wireless Ad hoc networks and satisfy the QoS requirements of multimedia sessions, multi-radio technique is introduced and stateless QoS model in single-interface single-channel—SWAN is extended to stateless QoS model in multi-interface multi-channel—MMSWAN. At the same time, a multi-interface multi-channel QoS routing protocol—MMQAODV is proposed, which is combined with MMSWAN to implement a cross-layer QoS guarantee mechanism. Simulation shows that the mechanism improves QoS of multimedia sessions and performances of best-effort sessions. In comparison with SWAN, end-to-end delay is reduced to its 2%~27% and delivered best-effort data are increased to 1.29~3.55 times of it.
