Summary:Software radios are emerging as platforms for multiband multimode
personal communications systems. Radio etiquette is the set of RF bands,
air interfaces, protocols, and spatial and temporal patterns that
moderate the use of the radio spectrum. Cognitive radio extends the
software radio with radio-domain model-based reasoning about such
etiquettes. Cognitive radio enhances the flexibility of personal
services through a radio knowledge representation language. This
language represents knowledge of radio etiquette, devices, software
modules, propagation, networks, user needs, and application scenarios in
a way that supports automated reasoning about the needs of the user.
This empowers software radios to conduct expressive negotiations among
peers about the use of radio spectrum across fluents of space, time, and
user context. With RKRL, cognitive radio agents may actively manipulate
the protocol stack to adapt known etiquettes to better satisfy the
user's needs. This transforms radio nodes from blind executors of
predefined protocols to radio-domain-aware intelligent agents that
search out ways to deliver the services the user wants even if that user
does not know how to obtain them. Software radio provides an ideal
platform for the realization of cognitive radio
