QAP maintains a polling list according to the accepted flows.
Obviously, the number of accepted flows of the modified admission control might be slightly decreased, but the video quality of accepted video flows is highly preserved.
AC schemes aim at guaranteeing flows' constraints in WMNs by accepting a new flow on the backbone mesh only if the latter is able to guarantee its quality of service (QoS) and the QoS of previously accepted flows.
In addition, the TXOP allocation mechanism located at QAP should account for maintaining the quality of accepted flows that might be degraded by the noisy channel environment.
Constraint 3 enforces that the new scheduling matrix of the network computed via Equation 19 is feasible, i.e., the scheduling made for previously accepted flows and the new flow are interference free.
Unfortunately, if the q i is slightly higher than δ 3 q ¯ i, then the particular flow will be granted with the high γ4 value, which causes low overall system utilization and less number of accepted flows.
Yield can be increased by adding a second stage and by introducing the accept flow of the second stage into the feed flow of the first stage.
The study of the hydraulic limits of reed beds, based on the knowledge of hydrodynamics in unsaturated porous media, shows the ability of the system to accept flow overloads.
In this solution, once every node on a flow path has accepted the flow in terms of bandwidth, the source has the final decision to accept or not the flow according to the decision made by the fuzzy decision scheme.
