Cognitive Radio based Smart Grid
Cognitive Radio based Smart grid (SG) can be seen as the future of elec-tricity transmission and distribution.
Smart grids are already substituting traditional power grids in a few developed nations and this change is both inevitable and
for the best. Smart grids powered by cognitive radio technology can efficiently understand energy requirements per user,
load and other fine and minute details without elaborate human intervention. In today’s world where non-renewable energy
sources are fast depleting, cognitive radio based smart grid network, if laid on a large scale can help save energy by lowering
wastage. For the smart grid to work effectively, Cognitive radio is made use of to communicate. In this backdrop, it’s
essential to allocate channels for this communication and transmission of data to take place in a Cognitive smart grid
network (CSGN). While most of the channels in 2G, 3G, 4G spectrum bands are under-utilized most of the time, the
Cognitive radio can function within this purview only, by making use of Primary User (PU) channels whenever they are not
in use. Primary Users are basically licensed (or allocated) channel. The identification, utilization and methodology of
utilization of available channels by Secondary User (SU) etcetera can be done by various algo-rithms; through this paper, we
have attempted to realise this.
