Abstract
In this paper, an improved method for bandwidth
allocation in a Cognitive Radio Network based on game theory
is presented. In this work, utility has been modified by inserting
weights to the three terms, received power, interference to other
links and interference from other links. Inserting weights enables
us to treat different CRN scenarios separately and appropriately
as per the requirement of the administrator. Moreover, a suitable
performance index for a CRN that considers throughput and
interference to other links has been introduced and is used
to evaluate different schemes. Being able to segregate and
individually treat the different utility terms has aided to analyze
and understand the CRN better and at a deeper level, which will
be helpful for further research work.
