Handoff Mechanism Using Spectrum Pool
In this paper, spectrum pool is one of the efficient techniques for spectrum sensing selection. Cognitive radio always preferred for accessing free channels efficiently with minimum handoff delay .The performance of spectrum pool has been implemented and compared with conventional handoff mechanism. Spectrum handoff occurs when primary user appears and the secondary users using this particular licensed channel. This particular spectrum handoff would use channels for the handoff process from the spectrum pool formed by proposed method. Spectrum sensing plays important role in case of cognitive radio. For accessing the spectrum reuse functionality, secondary users used to sense the radio frequency environment.
