Enabling unsubscribed Secondary User (SU) access through Dynamic Spectrum Access (DSA) techniques provides a huge opportunity to the Wireless Service Providers (WSPs) for achieving efficient radio spectrum usage as well as gain additional profits. This paper presents a novel and dynamic SU pricing model for implementation by the WSPs at their Base Stations (BSs) based upon a BS-centric distributed framework, that allows the SU price to vary dynamically with the changing radio spectrum usage at the BS. Assuming high competition among regional WSPs, a non-cooperative competition structure is considered among the WSPs, where neither information nor resources are shared among the WSPs. A simple single cell scenario easily scalable to multiple cells achieving competitive yet dynamic SU pricing among the BSs of two WSPs, is presented in this paper. The final SU price is seen to depend on the spectrum utilization at the BS, the wireless channel, and the price charged by WSPs to their PUs.
