Abstract

This paper focuses on spectrum handoff where cognitive user can returns the spectrum to demanded licensed user. Besides, the cognitive user can chooses to adjust its transmission power with sufficient protection to licensed user instead of carry out spectrum handoff. Using our proposed scheme, cognitive user switches between the bands if and only if it is unable to modify its transmission power within the tolerable limits. Therefore, this paper aims to clearly describe the concepts of cognitive radio and fuzzy logic, and the implementation of proposed algorithm. MATLAB software simulations were carried out and the results show the promising benefit of using our scheme in optimizing the power consumption and spectrum handoff rate of cognitive radio.
