Investigation of QoS Support of Wireless MAC Protocols

DA
State: completed by Alexander Müller

The key task of this thesis is to investigate on how QoS is supported in the existing IEEE 802.11 standards and afterwards design and simulate a TDMA-based (Time Division Multiple Access) MAC (Medium Access Control) protocol with QoS support for IEEE 802.11 networks. An investigation on existing approaches of TDMA-based MAC protocols for wireless networks should be performed and a summary of advantages and disadvantages of existing mechanisms shall be given.

A TDMA-based approach for a MAC protocol requires a scheduling component that decides timeslot assignement based on a bandwidth distribution algorithm. As infrastructure WLANs already have a central point, which is the access point (AP), the most straight forward approach is to utilize the access point control to define on how timeslots are assigned to different devices.
