Opportunistic Spectrum Access Study of CORAL Platform

As the requirement of spectrum is increasing with the advent of new technologies, cognitive radio networks have got tremendous attraction in recent days. Since the concept of cognitive radio is new, there are a few number of cognitive radio platforms have been introduced in the literature. CORAL is WiFi like cognitive radio platform developed by communication research centre (CRC) operated in license exempt band 2.4 GHZ and 5.8 GHZ. This platform is aimed to coexist with IEEE 802.11 network through TDD/TDMA access protocol. In this work, we have done some data analysis (collected by CRC) in order to determine interference statistics at the payload level. We have proposed a secondary user’s strategy in order to access the WiFi channels intelligently and afterward we have applied neural network in order to extrapolate traffic statistics during the future time interval.
