Abstract—We develop a new algorithm and performed a measurement for spectrum mobility in cognitive radio network. The operating frequency range is 2.4GHz to 2.5 GHz. An algorithm for spectrum handoff developed is able to make the cognitive user to produce efficient decision to return the spectrum to demanded licensed user. By using our proposed scheme, the cognitive user able to adjust its transmission power with sufficient protection to licensed user instead of carrying out spectrum handoff and it is found working nicely. In this project, measurement and simulation were implemented and provide agreement around 89% to 92%. The purpose is to analyze a new architecture for spectrum mobility and handoff with a sufficient level of Quality of Service guarantee by Internet System Provider for more energy efficient communications. Energy-efficiency of mobile networks not only reduces environmental impact, it also cuts network costs and helps to make communication more affordable for everyone.

Index Terms—Spectrum mobility, handoff, cognitive radio.
