On Green Cognitive Radio Cellular Networks: Dynamic Spectrum and Operation Management

Potential Game for Dynamic Spectrum Management in Cognitive Radio Networks

Dynamic spectrum management is one of the key technologies in cognitive radio networks, and more and more researchers have been paying much attention to algorithms and models for Spectrum sharing. In this paper, we present a dynamic spectrum management application model based on potential game. Firstly, the mapping relationship is constructed for sections in cognitive radio network and game the...

Dynamic Spectrum Access in Cognitive Radio Networks

Spectrum inefficient utilization and growing in demand of wireless services is one of the challenges facing the wireless communication systems as the spectrum is a finite resource. There is a need of better and smarter exploitation of the limited spectrum which will enables the usage and to allowing sharing of temporally unused spectrum allocated to the television broadcast service in non inter...

Spectrum Management in Cognitive Radio Wireless 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...
