Abstract: To solve the node and link failures in cognitive radio Ad Hoc networks,a novel master and slave mechanism based route,named MSMRC,for reliable communication between cognitive users was presented in this paper.The route takes the primary user activity patterns into account,and both the link reliable time and channel reliable time are also introduced to design this routing mechanism.When some routes fail,the existing communications between the cognitive users can be restored quickly through pre-configured slave routes.Experiments show that the proposed MSMRC method can significantly reduce the average overhead,and improve the packet delivery ratio and link repair rate,ensuring the quality of the network end to end communication services.
