A Novel Approach for Spectrum Access Using Fuzzy Logic in Cognitive Radio

In this paper, the authors have proposed a novel approach using Fuzzy Logic System (FLS) for the potential management of the spectrum access. They have used four descriptors such as spectrum utilization efficiency of the secondary user, mobility, distance of the primary user, and signal strengths of the secondary users. On the basis of these descriptors, there are 81 fuzzy rules have been setup, which are based on the linguistic knowledge. The output of the FLS provide the possibility of accessing spectrum band for secondary users and the user with the greatest possibility has to assigned the available spectrum band.
