The Dynamic Spectrum Market (DSM) is a key economic vehicle for realizing the opportunistic spectrum access that will mitigate the anticipated spectrum-scarcity problem. DSM allows legacy spectrum owners to lease their channels to unlicensed spectrum consumers (or secondary users) in order to increase their revenue and improve spectrum utilization. In DSM, determining the optimal spectrum leasing price is an important yet challenging problem that requires a comprehensive understanding of market participants' interests and interactions. In this paper, the authors study the spectrum pricing competition in a duopoly DSM, where two Wireless Service Providers (WSPs) lease spectrum access rights and Secondary Users (SUs) purchase the spectrum use to maximize their utility.
