Abstract

In cognitive radio networks, secondary users strive to exploit the frequency spectrum in the absence of primary users without causing interference through opportunistic access. However, the sudden return of primary users can cause serious interference and lead to an increase in channel switching in dynamic environments. Moreover, in platforms such as mobile ad hoc networks, user mobility adds to network instability and intensifies challenges such as routing. To address these challenges, this research presents a reactive routing protocol specifically designed for cognitive radio networks with mobile nodes. This protocol, by utilizing intersection analysis, mobility models, and advanced cognitive radio capabilities, results in a significant reduction in channel switching, decreased probability of interference between users, and optimal utilization of random channel access. Additionally, by eliminating dependency on a common control channel and increasing path stability through link expiration time calculation, it provides an efficient and cost-effective approach for establishing stable communications in dynamic networks.
