Description
Summary: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.
