Utilizing 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...
متن کاملMedium Access Control Design for Cognitive Radio Networks: A Survey
Designing a medium access control (MAC) protocol is a key for implementing any practical wireless network. In general, a MAC protocol is responsible for coordinating users in accessing spectrum resources. Given that a user in cognitive radio(CR) networks do not have priority in accessing spectrum resources, MAC protocols have to perform dynamic spectrum access (DSA) functions, including spectru...
متن کاملAn Implementation of Dynamic Spectrum Access on Handheld Radios
Dynamic Spectrum Access provides a group of radios with the ability to adapt to a changing RF environment by coordinating simultaneous changes to known, good frequencies amongst all radios in the group. This paper describes an implementation of DSA on a previously fielded software defined radio supporting networks of up to 16 radios. A TDMA protocol operating at the application level was used f...
متن کاملA survey on dynamic spectrum access protocols for distributed cognitive wireless networks
With the rapid development of wireless communications technologies, radio spectrum has become a type of extremely scarce resources in meeting the increasing demands for broadband wireless services. However, the traditional static spectrum allocation policy leads to severe spectrum underutilization and spectrum shortage problems. The cognitive radio (CR) technology can detect the occupancy of th...
متن کاملA Survey on Dynamic Spectrum Access Techniques in Cognitive Radio Networks
The idea of Cognitive Radio (CR) is to share the spectrum between a user called primary, and a user called secondary. Dynamic Spectrum Access (DSA) is a new spectrum sharing paradigm in cognitive radio that allows secondary users to access the abundant spectrum holes in the licensed spectrum bands. DSA is an auspicious technology to alleviate the spectrum scarcity problem and increase spectrum ...
