Cognitive radio technology free authorization through the use of opportunistic spectrum to improve spectrum utilization. Because in the cognitive wireless network, the communication between nodes must be without causing interference to the activities of the authorized user so you need to balance performance of cognitive wireless networks. This article puts forward a measurable spectrum joint routing algorithms, can in the spectrum sensing stage can't detect the level of the user's receiver to provide protection, and put onto a control channel routing information transmission, and from the perspective of energy efficiency design the routing discovery process, so that all in the middle of the forwarding nodes can get the spectrum or the network information, so in the destination node calculation consumption is also reduced.
