A New Spectrum Occupancy Model for 802.11 WLAN Traffic
Anurag Gupta, Satyam Agarwal, Swades K. De · IEEE Communications Letters · 2016
We report characterization of busy and idle periods in 802.11 wireless local area network via experiments in software-defined radio. A new channel occupancy model, called the Gaussian mixture (GM) model, is proposed and shown to fit the empirical data significantly better than the other available models. Further simulation results demonstrate that utilizing the GM model highly improves secondary user goodput and energy efficiency.
