ABSTRACT: In mobility management, detection of
spectrum hole plays very important role for doing spectrum handoff mechanism.
Operation of the cognitive radio depends on the spectrum sensing which is the
most important task in case of cognitive radio network. Detection of spectrum
holes (underutilized sub-bands of the radio spectrum) estimates average power,
throughput and utilized time for each spectrum hole. But in case of reactive
spectrum handoff mechanism, spectrum handoff delay becomes tedious task. So in
order to make spectrum handoff mechanism efficient our scheme proposed spectrum
handoff mechanism with negligible spectrum handoff delay. In this paper we had
real time experimental setup with the spectrum handoff mechanism. We
investigate algorithm for spectrum handoff mechanism which strongly minimizes
spectrum handoff delay of cognitive radio network using spectrum detection
method for sensing spectrum holes.
