Price-Based Spectrum Management in Cognitive Radio Networks

interference management in cognitive radio satellite networks based on time and spectrum sensing

in this paper, an interference management for multi-beam satellite network to enhance spectral efficiency is studied. first, a two-satellite for future generation satellite network using cognitive radio technology is provided.this network is composed of a secondary satellite and aprimary satellite where the primary satellite system does not suffer from severe destructive interferences coming fr...

Hypernetworks based Radio Spectrum Profiling in Cognitive Radio Networks

This paper presents a novel concept of active radio spectrum profiling f or C ognitive R adio ( CR) networks using evolutionary hypernetworks. Spectrum profiling enables cognitive radio nodes to abstract and predict usable spectrum opportunities in pre-defined P rimary U sers ( PU) c hannels. T he P U c hannels a re actively monitored through spectrum sensing and the resulting binary time serie...

The Spectrum Sharing in Cognitive Radio Networks Based on Competitive Price Game

The competitive price game model is used to analyze the spectrum sharing in the cognitive radio networks. This paper focuses on the improved spectrum sharing problem with constraints of available spectrum resource from primary users. The constrained spectrum sharing model based on competitive price game is established. In order to achieve the spectrum sharing strategy that satisfies the constra...

Issues and Challenges in Spectrum management in Cognitive Radio Networks

Cognitive radio is a revolutionary technology that allows efficient, adaptable and intelligent use of spectrum without causing interference to the current licensed users. For cognitive radio adaptability, optimal usability and the power to evolve are the major factors that set apart an evolutionary machine. This paper introduces the concept of spectrum and network heterogeneity in case of cogni...
