Online Pricing of Secondary Spectrum Access With Unknown Demand Function
The authors consider a wireless provider who caters to two classes of customers, namely Primary Users (PUs) and Secondary Users (SUs). PUs has long term contracts while SUs are admitted and priced according to current availability of excess spectrum. The average rate at which SUs attempt to access the spectrum is a function on the currently advertised price, referred to as the demand function. They analyze the problem of maximizing the average profit gained by admissions of SUs, when the demand function is unknown.
