DISTRIBUTED WEIGHTED COOPERATIVE CONSENSUS ALGORITHMS FOR DYNAMIC SPECTRUM ACCESS
In the last few decades, there has been an enormous increase of wireless communication systems. The usage of frequency bands, or spectrum, is strictly regulated by the Federal Communications Commission (FCC). The spectrum is assigned to licensed users also known as primary users (PU). However, various measurements of spectrum utilization have shown unused resources in frequency, time, and space, resulting in the spectrum to be underutilized. Cognitive radio (CR) aims to improve spectrum utilization by allowing the use of licensed spectrum in an unlicensed manner by users who have no spectrum ...
