CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Wireless ATM networks, which are currently under investigation, promise to support future multimedia applications. The medium access control (MAC) protocol of such systems plays a key role in providing differentiated quality of service (QoS). A variety of proposed MAC protocols use a centrally controlled flexible. The Medium Access Control (MAC) protocol and the underlying traffic scheduling schemes defined in the Wireless ATM Network Demonstrator (WAND) system being developed within project Magic WAND are presented. Magic WAND is investigating wireless ATM technology for customer premises networks in the framework of the Advanced Communications. Fair Queueing Wireless ATM MAC Protocols. In order to support differentiated QoS the base station scheduler must allow a fair sharing of the available resources depending on the requested QoS. Moreover it should be insensitive against partially outdated status information of the mobile station queues. Our proposed scheme is able to support Author: Rolf Sigle and Thomas Renger.

Various scheduling schemes such as Fair Scheduling [45], Distributed Fair Scheduling [46], Channel State Dependent Round Robin (CSD-RR) [47], Token Bank Fair Queuing (TBFQ) for Wireless . A wireless ATM network is expected to offer services similar to those of a fixed ATM network. In the fixed In the fixed part, scheduling and CAC techniques, introduced for fixed ATM, can be used. The Medium Access Control (MAC) protocol defined in the Wireless ATM Network Demonstrator (WAND) system being developed within the project Magic WAND is presented. Magic WAND is investigating extensions of ATM technology to cover wireless customer premises networks, in the framework of the Advanced Communications Technologies and Services (ACTS) programme, funded . In this paper, we present a prototype of an overlay network that provides Quality of Service routing for flows in an ad-hoc wireless network. A distributed scheduler offers MAC layer reservation.

The medium access control (MAC) protocol of such systems plays a key role in providing differentiated quality of service (QoS). A variety of proposed MAC protocols use a centrally controlled flexible allocation of time slots. In order to provide a fair scheduling, the mobile stations must inform the base station about the state of their queues. Indeed, MAC protocols for a wireless ATM network in which user traffic requirements are highly heterogeneous (classified into CBR, VBR, and ABR), are even more intricate to design.

Since the fluid algorithm converges to the maxmin fair rates under asynchronous distributed operation, the slotted one is ex-pected to have similar properties. It should be noted that the maxmin fairness objective in slot-ted multi-channel wireless systems was first addressed.
