چکیده

One of the main challenges in dispersed cognitive radio networks is establishing a shared channel for the secondary users' interactions and conveying control messages. This channel is limited and exclusive to cognitive radio users. In today's era, wireless devices, through their applications, lead to an increase in the demand for spectrum utilization. Consequently, we will witness a high influx of information requests and increased users seeking access to the shared channel. This paper aims to introduce a new method of establishing a shared channel through a transmitter or receiver and a backup channel in dispersed cognitive radio networks. We intend to demonstrate that any user with a radio card and cognitive capabilities can be accommodated through this approach. The proposed method not only creates a meeting channel for secondary users, but the network operation is also continuous. What makes this method innovative and pioneering is its utilization of the backup channel in a stored manner. Based on the simulation results, the۲presence of multiple input nodes in this pattern exceeds the method proposed by national foundations, including South Korea's national research. The implementation time in this method is significantly lower, and the flexibility is according to the above results.
