摘要

QoS provisioning is not an easy problem under the time varying and dynamic environment of MANET.Based on MANET Adaptive QoS Framework(MAQF)and through improving the scheme of MACA/PR,a new mechanism MAQF/MAC that can provide MAC layer QoS guarantees for MANET has been presented.MAQF/MAC can measure the variation of resource in real time,change the channel access policy and adapt the amount of resource captured by trafflc.In addition,this paper also concerns some key components of MAQF/MAC,including reservation table(RT),QoS routing,resource compression algorithm and etc.Simulation result show that MAQF/MAC ls superior to MACA/PR in the aspects of multi-level trafflc QoS provisioning and resource utilization.
