The Design of an Effective Extreme_Controller_Mechanism Scheme for Software-Defined Cognitive Radio Network

Security is a major concern in Software Defined Cognitive Radio Network (SDCRN). SDCRN is an integration of the Software Defined Network (SDN) with the Cognitive Radio Network (CRN). SDN is an architecture developed to reduce the complexity of the network, whereas CRN is a technology developed to allow radios to learn and adapt to their environment. However, the architecture and technology are susceptible to a number of malicious attacks such as Distributed Denial of Service (DDoS) and Primary User Emulation (PUE), respectively. The DDoS and PUE attacks could be launched onto the SDCRN with the intention of disrupting service. The design of effective security schemes that enhance maximum protection of SDCRN from these malicious attacks is a sought after solution in network security. Hence, this research study proposes a security mechanism that addresses the effects of DDoS and PUE attacks in SDCRN.
