With the current increase in wireless technology, spectrum is becoming scarce. By equitably allocating frequency bands to unlicensed and licensed clients, the cognitive radio network (CRN) reduces issue of growing inadequate utilization and spectrum scarcity. Secondary users (SUs) and unlicensed users are given the opportunity to impulsively exploit the licensed users allotted free spectrum under CRN. The rendezvous procedure, in which SUs gather on widely used channels and create trustworthy linkages for efficient communication, is the key step in the creation of CRN. Considering the dynamic context of CRNs, rendezvous methods that depend with the presumption of common control channel (CCC) across SUs are less effective and impractical. Thus, the rendezvous among SUs is often accomplished via the channel hopping (CH) approach without CCC assistance, also known as blind rendezvous. The complete asynchronous symmetric rendezvous (CASR) technique presented in this paper ensures that SUs will rendezvous in a finite amount of time without the need for time synchronization. The CASR method uses the SU's MAC address as a means of generating a unique identifier (ID) and creating a CH sequence by dynamically adjusting the ID in accordance with the number of accessible channels for communicating. The CASR method was successful in achieving rendezvous assurance while maintaining an acceptable time to rendezvous by utilizing the distinct ID of each SU. The effectiveness of the CASR technique is theoretically evaluated and empirically tested through several simulation studies. According to simulation studies, CASR technique outperforms existing rendezvous techniques when considering of average time-to-rendezvous.

During the last decade, Cognitive Radio Network (CRN) technology has been a significant advance in addressing the ever-increasing spectrum demand. As the number of licensed and unlicensed users in a network rises to complete a certain activity, the information exchange between various types of traffic becomes more complex and difficult. Congestion in CRN is also caused by the conflict among several users for channel access (PUs and SUs). In a very crowded network, many applications perform badly owing to packet collisions and, as a result, packet loss before significant buffer queue building. This circumstance is aggravated by an increase in network users. Congestion control is a vital and essential aspect of the present research issue in communication networks. Several recent reviews in the literature indicate that the congestion issue in the CRN has not been thoroughly studied. Thus, effective and efficient congestion control strategies are sought to optimize network resource usage and management. To prevent congestion, it is crucial for CRN to do research on the creation of an efficient congestion management system. This will improve the network's resource consumption and performance. "Performance improvement via efficient spectrum management through optimum resource management and congestion control in the CRN by mitigating different threats" is the primary target of this project. This research also focused on enhancing performance by addressing security issues in an IoT-based CRN environment. This study provides a comprehensive review of several similar studies and their limitations, which may be used to formulate a new research target.
