摘要
针对IEEE802.22的无线地域网(WARN),首次,建立了考虑用户移动性的认知无线网络频谱移动管理的数学模型,更加真实地描述了认知无线网络中的用户行为,利用马尔科夫模型对提出的系统进行了仿真与分析。在此基础上,为了改善系统性能,还提出了带有切换保护信道的马尔科夫模型。
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.
