We propose a MAC protocol for cognitive radioenabled secondary networks, which opportunistically use the channels of CSMA/CA-based primary network. We have considered IEEE 802.11 WLAN as a de facto primary network in ISM band. Our study focuses on a single WLAN channel that is used by a WLAN client and server for HTTP-based web browsing application. We use the theory of alternating renewal processes to model the occupancy of channel by WLAN nodes. This model is used by a pair of secondary nodes… CONTINUE READING
