(English Abstract) |
Cognitive Radio Network(CRN) is one of areas pormising to enhance to spectrum utilization by using unlicensed users to exploit the spectrum in an opportunistic manner. In CRN, the function of detection idle frequencies is so impoprtant. Due to the randomness of the appearance of Primary Users, disruptions to communication of Secondary Users are often difficult to prevent. this may also lead to low throughtput of CRN. The state of each channel at any time, either idle(unoccupied by a PU) or busy (occupied by a PU), is hidden with CRN, With this observation, we proposed the Hidden Markov model to validate the state of each channel which determines the spectrum handoff for CRN. In our propose framework, we also simulate this method with random channel selection in proactive spectrum handoff framework.
