IEEE 802.11 wireless LANs (WLANs) have been rapidly deployed all over the world at numerous cities, enterprises and universities. These networks provide high bandwidth to mobile users by deploying low-cost wireless access points. Today, billions of mobile devices use IEEE 802.11 technology for numerous applications. In spite of their success, WLANs suffer from several serious shortcomings, including lack of fair service and inability to provide quality of service (QoS) guarantees to real-time (RT) applications. In this talk, I will show the fairness limitations of WLANS with simple examples and discuss the challenges of providing fairness as well as QoS support in WLANs without changing the standard.
