4TH INTERNATIONAL CONFERENCE ON COGNITIVE RADIO AND ADVANCED SPECTRUM MANAGEMENT

Description: :: Theme Cognitive and Self-Organizing Networks for Disasters Aftermath Assistance :: Scope Conventional fixed spectrum allocation cannot successfully cope with the scarcity of radio frequency spectrum. Cognitive radio is a novel technology, which improves the spectrum utilization by seeking and opportunistically utilizing radio resources in time, frequency and space domains on a real time basis. The cognitive radio technology poses many new technical challenges, and overcoming these issues becomes even more challenging due to non-uniform spectrum and other radio resource allocation policies, economic considerations, the inherent transmission impairments of wireless links and user mobility. Cognitive radio technology advances are based ...

The 3rd International Workshop on Cognitive Radio and Advanced Spectrum Management

Description: "Today's wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. This new networking paradigm is referred to as cognitive radio networks." by Ian F. Akyildiz "Cognitive radios are aware of their environment and intelligently adapt their performance to the user's needs. A CR is a ...
