Detection of spectrum in cognitive radio network for efficient spectrum handoff mechanism

In cognitive radio communication, spectrum sensing is the most important task upon which operation of cognitive radio depends on. Detection of spectrum holes before taking the decision of spectrum handoff mechanism is very important which minimizes the service time required for spectrum handoff mechanism. In this paper we used real time experimental setup with the spectrum sensing results for the design of algorithm for spectrum handoff mechanism which strongly minimizes spectrum handoff delay of handoff mechanism in cognitive radio network.
