Abstract of Talk
An Economic Framework for Dynamic Spectrum Access and Service Pricing
Abstract: In this talk, we will understand what Dynamic Spectrum Access (DSA) is and why is there such a thrust by federal agencies and the community at large. We will discuss the concept of DSA that will allow the radio spectrum to be traded in a market like scenario allowing wireless service providers (WSPs) to lease chunks of spectrum on a short-term basis. Currently, there is little understanding on how such a dynamic trading system will operate so as to make the system feasible under economic terms. Therefore, consistent economic models must be used to guide the dynamic spectrum allocation process and the resource management algorithms that the providers use such that there are sufficient incentives for the providers to provide better and newer services.
We will analyze the overall system (i.e., spectrum allocation and interaction of end users with the WSPs) from an economic point of view.
We will propose an auction model that dynamically allocates spectrum to the WSPs based on their bids and maximizes revenue and spectrum usage.
We will borrow techniques from game theory to capture the competition among WSPs and propose a dynamic pricing strategy; existence of price equilibrium will also be shown. Some preliminary results, obtained through simulations, will also be presented.
