Abstract
The second method that relies on advanced MAC layer scheduling and MAC layer resource monitoring. Such a MAC layer approach is able to achieve low message overhead and can easily adapt to the dynamics of the network. For the MAC layer approach, this thesis includes four novel MAC layer scheduling algorithms based on dynamic contention window control: DDA for delay assurance to realtime traffic, DBA for throughput assurance to realtime traffic, BEP for rate policing of best effort traffic and GCA for flexible and efficient bandwidth allocation of best effort traffic. This thesis also describes a novel framework, QPART, that provides reactive admission control for a MAC layer approach. All these schemes are fully distributed and can support a variety of resource allocation policies without requiring communications among neighboring nodes.
