Broker Based Secondary Spectrum Trading

Abstract

Radio spectrum license is multi-dimensional in nature. This suggests that matching a bid to buy and an offer to sell has to be done across the multiple dimensions to maximize spectrum usage in terms of economic efficiency. In addition, creating a functioning secondary market for trading spectrum requires an intermediary for both pooling the resources and matching the supply and demand sides of the equation. This paper proposes a multiple-dimension auctioning mechanism through a broker to facilitate an efficient secondary spectrum market. A broker for orchestrating the market is proposed describing its basic functionalities. Two trading negotiation protocols, i.e., merchant and auction, are discussed. Focusing on the auction mode, the multiple-winner determination problem (mWDP) is defined and cast into a multidimensional multiple-choice knapsack problem (MMKP). Since the MMKP is NP-complete, two heuristic algorithms to solve the mWDP namely (1) area-by-area (ABA), and (2) maximum-utility-first (MUFA) are presented. Numerical studies illustrating the potential of the algorithms are presented. The numerical studies indicate that MUFA is better in addressing the exposure problem.

Dynamic Spectrum Sharing Optimization and Post-Optimization Analysis With Multiple Operators in Cellular Networks

“…Interests in this context include secondary leasing and pricing strategies among incumbent spectrum license holders, SNOs and secondary users. These prior studies mainly focused on approaches using auction mode and game theory to implement the spectrum pricing and allocation schemes by taking into account the variation of the networks demands and constraints such as power, price and interference [10,11,[15][16][17][18]20].…”

“…In [20], the authors proposes a multiple-dimension auctioning mechanism through a broker to facilitate an efficient secondary spectrum market. Auction schemes where a central clearing authority auctions spectrum to bidders, while explicitly accounting for communication constraints is proposed in [21].…”

Modelo de muestreo comprimido multiespectral para radio cognitiva

“…Por ejemplo, en [54], un BB es usado para asignar ancho de banda a unos usuarios dentro de una femtocelda. De acuerdo con el contexto en que un SB es usado y las funciones que implementa, toma nombres como Bandwidth Broker [55], Spectrum Policy Server [51], Regional Spectrum Broker [53] o simplemente Broker [56]. En todos estos escenarios, el SB es la entidad responsable de ejecutar tres de las cuatro funciones básicas definidas para radio cognitiva: Seleccionar los canales disponibles (Spectrum Decision), coordinar el acceso a estos canales entre usuarios disponibles (Spectrum Sharing), y desocupar los canales cuando un UP es detectado (Spectrum Mobility) [3].…”

Spectrum Sharing Optimization in Cellular Networks under Target Performance and Budget Restriction

“…In [23], the authors proposes a multiple-dimension auctioning mechanism through a broker to facilitate an efficient secondary spectrum market. In [24] a knapsack based auction model that dynamically allocates spectrum to the wireless service providers (WSPs) such that revenue and spectrum usage are maximised.…”
