Fair queuing in wireless networks: issues and approaches

摘要

Fair queuing has long been a popular paradigm for providing bounded delay channel access and separation between flows in wireline networks. However, adapting fair queuing to the wireless domain is not a trivial task because of the unique problems in wireless channels such as location-dependent and bursty channel error. In this article we identify the key issues in wireless fair queuing, define a wireless fair service model, present a generic framework for designing wireless fair queuing algorithms, and explore solutions within this framework. Using simple examples, we show that some of the wireless fair queuing algorithms proposed in literature can achieve wireless fair service.
