QGMA: A New MAC Protocol for Supporting QoS in Wireless Local Area Networks

In this paper, we propose a novel MAC protocol, called Quality-ofservice Guarantee Multiple Access (QGMA), in wireless local area networks to support the quality of service required by embedded real-time applications and multimedia-integrated distributed control. As compared to other existing MAC protocols, QGMA achieves high system utilization, and provides a deterministic bound on the connection establishment delay and temporal QoS for real-time applications. In particular, by having the base station handle resource arbitration and utilize different scheduling algorithms to arbitrate access to data slots on a wireless channel, mobile hosts (MHs) are relieved from the burden of coordinating all the ongoing activities, and moreover, different levels of temporal QoS can be easily achieved.
