摘要:A cognitive radio engine (CE) is an intelligent agent which observes the radio environment and chooses the best communication settings that best meet the application’s goal. In this process, providing reliable performance is one of the major tasks in designing CEs for wire...

摘要:Abstract(#br)In this paper, we propose a novel algorithm for improving spectrum sensing in cognitive radio networks by forming coalitions among cognitive radio users in a fading channel environment. We use concepts from matching theory, specifically the stable marriage problem, t...

摘要:... However, cognitive radio (CR) provides more spectral opportunities through opportunistic-use of unused licensed spectrum while ensuring minimal interference to licensed users. Similarly, spectrum handoff, which is a new type of handoff in cognitive radio, has the potential to...

摘要:Abstract(#br)Rendezvous in cognitive radio ad-hoc networks is an essential step for a pair of unknown cognitive radio (CR) users to initiate a communication. Most of the existing studies address rendezvous problems as a design of a search strategy to meet on the same channel at t...

摘要:Abstract(#br)Cognitive radio technology addresses the problem of spectrum scarcity by providing an opportunity for secondary users to exploit the unutilised licenced spectrum. However, constant interference from primary users makes reliable communication extremely challenging for...

摘要:Abstract(#br)Cognitive radio ad hoc networks are commonly perceived as ideal ad hoc environments where cognitive radio technology enables secondary users (SUs) to utilize scarce spectrum resources in a dynamic manner. Cooperative spectrum sensing (CSS) is the key function of cognitive radio...
