| Summary: | Cognitive radio (CR) is a paradigm for wireless communication in which a
wireless node changes its transmission or reception parameters to communicate
efficiently avoiding interference with licensed or unlicensed users. The utilization
of spectrum is one of the critical issues in development of cognitive radio.
Therefore, channel selection algorithm is developed to select the best operating band
which can maximize the total system performances. This project study the
spectrum co-existence between IEEE 802.16a and 802.11b network in the same
un-licensed band using cognitive radio technique. A channel selection algorithm is
proposed to improve the secondary user's throughput and avoid interference with
primary user. NS2 simulation model is presented to evaluate the channel selection
in scenarios with co-existing IEEE 802.16a and 802.11b network |
