In this paper, The Concept of Adaptive Routing in Cognitive Radio Mobile Ad-Hoc Network (CR-MANET) is proposed. Cognitive Radio (CR) is technology that is widely considered as a promising technology to solve the problems in wireless networks resulting from the limited available spectrum and the inefficiency in the spectrum usage. It is an enabling technology that allows unlicensed (secondary) users to exploit the spectrum allocated to licensed (primary) users in an opportunistic manner. While in classical CR networks the central network entity such as a base-station in cellular networks is responsible for spectrum and routing management, in CR-MANET networks this responsibility lies on end-user devices. Therefore, routing protocols in CR-MANET need to be robust and must adaptively cooperate with spectrum sensing methods. The proposed Concept of Adaptive Routing in CR-MANET is therefore composed of function blocks that are able to perform spectrum sensing, intelligent channel management and adaptive routing.
