Abstract
In this paper, we design an efficient scheduler for Mesh Deterministic Access (MDA) in IEEE 802.11s-based Wireless Mesh Networks (WMNs), called Enhanced Differentiated MDA (ED-MDA). ED-MDA is combined with an Efficient Admission Control algorithm, called EAC, that guarantees QoS for different service classes and provides higher capacity in WMNs. EAC processes both new and HandOver (HO) calls to maintain a balance between two conflicting requirements: maximizing the resource utilization and minimizing the dropping rate. To establish priority between new and HO calls, especially to avoid the forced termination of an ongoing call, ED-MDA coupled with EAC reserves the minimum amount of necessary resources while maintaining an acceptable HO call dropping rate and high resource utilization. Particularly, our model provides an efficient adaptive adjustment of the Contention Free Period (CFP) duration to make efficient use of the scarce wireless resources while supporting different services with different QoS requirements, such as delay. Simulations show that ED-MDA together with EAC outperforms existing schemes.
