To avoid interfering with the main users of cognitive users and achieve mobility requirements of the spectrum,a spectrum sharing and access protocol in Ad Hoc cognitive radio network is proposed.Firstly,the frame of network based on the Ad Hoc cognitive radio network is formed.Choosing spectrum for sensing based Markov model is set forth.Cognitive users sense the chosen spectrum but not the whole spectrum to low down the needs of equipment capability and save energy.At the end,the algorithm of cognitive radio spectrum access and spectrum allocation is given in order to maximizing the benefits.
