| Abstract: | For IEEE802.22 wireless area network （WARN）,this paper was established to consider user mobility of cognitive wireless network spectrum mobility management for the first time.It described user＇s behavior in cognitive radio network more realistically,and performance analysis of the proposed Markov model was presented.On basis of this,this paper also established another MARKOV model with handoff reservation channel to improve the performance. |
