Abstract: As unlicensed users that have lower priority in spectrum usage often cause interference to licensed users in a wireless network, there is a need to provide a method to reduce the problem. The present invention aims to reduce the interference by improving the spectrum sensing capability of unlicensed users through distribution of collected data from the licensed users such as spectrum holes, unavailable channels, interference temperature and presence of the licensed users detected from licensed users among unlicensed users of each clusters and exchange of the data with other clusters. The steps involved in this method include forming clusters consisting of unlicensed users in which a cluster head is selected for each cluster. The unlicensed users collect data of the surrounding radio spectrum band and distribute it among other unlicensed users of the same cluster. The cluster heads also exchange the collected data among themselves to further disseminate the exchanged collected data to other members of the clusters. An available channel is selected based on the collected data for data transmission among the unlicensed users. By doing so, the unlicensed user could move into the available channel and performs data transmission with its counterparts without causing much interference to the licensed users in the wireless network.
