Design for cognitive radio Ad Hoc networks
Zhao Yiyun · Applied science and technology · 2011
For meeting the demand for research on the channel allocation algorithm of cognitive radio Ad Hoc networks,an extension model of cognitive radio Ad Hoc Networks,based on NS2,is proposed.It uses a CM(channel management) class,which learns from Czou's ideas,to manage channels information,to implement channel selection algorithm and to update channels states.It adopts dedicated common control channel,which is used for exchanging the control information and broadcasting.A node chooses a channel for data transmission according to the channel selection rules.The simulation results indicate that the system is reasonably designed,and it can satisfy study of the channel allocation algorithm based on data link.
