Cognitive Radio: An intelligent Device for Dynamic Spectrum Access (DSA) and Radio Resource Management (RRM)

Radio spectrum is a scarce and non-reproducible natural resource hence spectrum management policies play a vital role in ensuring the efficient use of spectrum. Optimum usage of radio resources will be done by sharing these resources among various radio services. Last two decade has seen a tremendous growth in Indian telecommunications because of effective policies launched by governing body and effort of entrepreneurs. As the growth is fast the spectrum access demands are increased enormously. The increasing demand of spectrum imposes spectrum management policies as well as various issues in management of telecommunication domain. As radio resource is limited; the resource needs must be efficiently shared and reused by a number of users who may be simultaneously accessing a variety of mobile services. This paper investigates the cognitive radio resource management using game theory. Cooperative game theory provides the shared radio resources fairly among multiple non cooperative cognitive radio networks to optimize overall performance.
