Dynamic Spectrum Leasing with Two Sellers
This paper studies dynamic spectrum leasing in a cognitive radio network. There are two spectrum sellers, who are two primary networks, each with an amount of licensed spectrum bandwidth. When a seller has some unused spectrum, it would like to lease the unused spectrum to secondary users. A coordinator helps to perform the spectrum leasing stage-by-stage. As the two sellers may have different ...
متن کاملDynamic Spectrum Leasing (DSL) in Dynamic Channels
Dynamic Spectrum Leasing (DSL) was recently proposed in [1]–[4] as a new way to achieve dynamic spectrum sharing (DSS). Unlike previously considered dynamic spectrum access (DSA) proposals, DSL allows for the spectrum owner, called the primary user, to dynamically adjust the amount of interference it is willing to tolerate from secondary users. In response, the secondary users update their tran...
متن کاملDynamic Spectrum Leasing (DSL): A New Paradigm for Spectrum Sharing in Cognitive Radio Networks
Recently [1] proposed a dynamic spectrum leasing (DSL) paradigm for dynamic spectrum access in cognitive radio networks. In this paper, we formalize this concept by developing a more general game theoretic framework for the dynamic spectrum leasing and by carefully identifying requirements for the coexistence of primary and secondary systems via spectrum leasing. In contrast to hierarchical spe...
متن کاملLearning to Thrive in a Leasing Market: An Auctioning Framework for Distributed Dynamic Spectrum Leasing (D-DSL)
Recently proposed dynamic spectrum leasing (DSL) for dynamic spectrum sharing (DSS) presumes that there is a reward for primary users for accepting secondary activity. The reward primary users received in previous DSL proposals, however, were considered to be proportional to the secondary interference level. In this paper, we propose a new way to encourage primary users to lease their spectrum:...
متن کاملUtilizing dynamic spectrum leasing for cognitive radios in 802.11-based wireless networks
Dynamic spectrum access (DSA) is proposed to deal with the growing shortage of available leased spectrum for wireless communication. We investigate a subset of DSA referred to as dynamic spectrum leasing (DSL). At its core, DSL allows spectrum lease holders and cognitive radios to cooperate in an effort to leverage spatial diversity to improve channel utilization for both parties. In this resea...
