Routing in cognitive radio networks faces several problems including the primary user appearance, the route establishment, maintenance delay, and the secondary users competition to share the channels. This paper proposes Load Balancing Routing in Cognitive Radio Ad-Hoc Networks (LBR-Cognitive) to reduce the effect of these problems by making load balancing between routes, so the traffic division per routes varies according to the primary users' activities. Moreover, the data starts to be sent to the destination earlier than any other cognitive radio routing protocol as the source doesn't wait until reception of the acknowledgement from the final destination itself. Instead, the source starts to send as soon as a segment acknowledgement (SEGACK) or final destination acknowledgement is received, which reduces the delay caused by route establishment compared to other cognitive radio routing protocols. The paper results illustrate the delay margin below the application acceptable delay.
