Congestion Game Models for Capacity and Bandwidth Relation in Dynamic Spectrum Access

Dynamic spectrum access is a technique to utilize the spectrum resources efficiently in a cognitive radio environment. To use spectrum efficiently various models were designed by researchers. Game theoretical models are few of the efficient techniques recently introduced in wireless communications. Game models are very useful for opportunistic selection of spectrum and help to utilize available spectrum efficiently. We introduced the spectrum underlay model and discussed the current state of allocation algorithms. We then introduced the congestion game model for opportunistic spectrum access with minimum interference. The theoretical results conclude that the congestion game model helps to use the underlay spectrum efficiently with minimum interference.
