Measurement-Based Models for Cognitive Medium Access in WLAN Bands
Stefan Geirhofer, Lang Tong, Brian M. Sadler · 2007
This technical report corroborates the design of Cognitive Medium Access (CMA), a protocol enabling coexistence with multiple parallel WLAN channels by keeping interference below a given constraint. The derivation of CMA in [1] is solidified by measurement-based models, including an experimental study of the physical layer interaction between both systems, as well as a stochastic model allowing to predict the WLAN’s medium access. Due to space limitations our paper [1] focused on the derivation of CMA and provided only the main results of our experimental studies. In this technical report we cover the measurement aspect in detail and provide additional information to substantiate our results.
