— In this paper we propose Cognitive Medium Access (CMA), a protocol aimed at improving coexistence with a set of independently evolving WLAN bands. A time-slotted physical layer...
In this paper we design a cognitive radio that can coexist with multiple parallel WLAN channels while abiding by an interference constraint. The interaction between both systems is...
— The coexistence and interworking of IEEE 802.16 and IEEE 802.11 is an acute problem. The frame-based medium access of 802.16 requires rigorous protection against interference f...

Spectrum regulation will undergo elementary changes in the near future allowing a less restricted and more flexible access to radio spectrum. Intelligent radios, socalled cognitive...

— We present the unfairness problem between the uplink and the downlink flows in the IEEE 802.11e infrastructure Basic Service Set (BSS) when the default settings of the Enhance...
