Summary:Wireless multimedia applications require significant bandwidth,
some of which will be provided by third-generation (3G) services. Even
with substantial investment in 3G infrastructure, the radio spectrum
allocated to 3G will be limited. Cognitive radio offers a mechanism for
the flexible pooling of radio spectrum using a new class of protocols
called formal radio etiquettes. This approach could expand the bandwidth
available for conventional uses (e.g. police, fire and rescue) and
extend the spatial coverage of 3G in a novel way. Cognitive radio is a
particular extension of software radio that employs model-based
reasoning about users, multimedia content, and communications context.
This paper characterizes the potential contributions of cognitive radio
to spectrum pooling and outlines an initial framework for formal
radio-etiquette protocols
