In this paper we propose a centralized spectrum auction method in a DSA framework to distribute spectrum for fixed infrastructure wireless networks. To achieve a feasible, efficient and optimal allocation, a one-shot, multi-bid auction method together with a second-price pricing scheme is proposed. We prove that, by fixing the slow varying parameters of the model the feasibility check becomes a set separation problem in the request-space. Furthermore, based on this observation we propose a method to determine the separation hyper surface. However, when the allocation is not feasible an exhaustive search over the hyper-space is required. We also show how the scalability of this calculation can be improved by defining a so-called exclusion matrix as a pre-calculation filter.

Creating a "spectrum market" is a possible solution to distribute spectrum efficiently. In this paper we propose an auction method with a pricing scheme developed in a Dynamic Spectrum Allocation (DSA) framework that handles interference issues in a flexible way. We take interference into account as a source of spectrum utilization degradation, captured by the so-called geographical coupling and technology coupling parameters. We propose a one-shot multi-bid pricing scheme that takes the special properties of DSA into account. For an efficient spectrum brokering, there should be a strong incentive for users to accommodate each other. The idea behind the proposed pricing method is to charge providers that do not tolerate others and cause large interference to other regions. A simulation example is also given to highlight the achievable gains using our proposed solution.
