Spectrum sharing and cognitive radio [PDF]
2009 International Conference on Ultra Modern Telecommunications & Workshops, 2009 Spectrum sharing has been the subject of a 3 year research programme organised by the UK's Virtual Centre of Excellence in Mobile and Personal Communications. Cognitive radio was identified as a key enabling technology to allow spectrum to be shared efficiently between terminals and networks.

International Journal of Distributed Sensor Networks, 2012 Spectrum sharing fairness is an important topic in cognitive radio ad hoc networks (CRAHNs) and cognitive radio sensor networks (CRSNs). Consensus-based protocols can provide light-weight and efficient solutions for CRAHNs and CRSNs but the theoretical ...

A Cloud-Based Architecture for the Internet of Spectrum Devices Over Future Wireless Networks
IEEE Access, 2016 The dramatic increase in data rates in wireless networks has caused radio spectrum usage to be an essential and critical issue. Spectrum sharing is widely recognized as an affordable, near-term method to address this issue. This paper first characterizes

Spectrum sharing with secure transmission [PDF]
EURASIP Journal on Wireless Communications and Networking, 2014 In this paper, we propose a cooperative scheme between primary and secondary networks. In this scheme, a secondary user (SU) accepts a lease of a part of the licensed band according to a cooperative request of a primary user (PU). Hence, the SU helps the PU in transmitting primary signals and has an opportunity to access the frequency spectrum.

Network slicing with spectrum sharing strategy in cognitive capacity harvesting network
Tongxin xuebao, 2021 To realizing the network slice with spectrum sharing in cognitive capacity harvesting network, a spectrum sharing strategy was proposed based on 4D conflict graph and opportunistic capacity.Firstly, a 4D conflict graph model for mesh network was built ...

Competition with licensed shared spectrum [PDF]
2014 48th Annual Conference on Information Sciences and Systems (CISS), 2014 This paper considers sharing wireless spectrum via licensed secondary access in which a single firm has an exclusive license for secondary use of a spectrum band. Building on previous work modeling competition among wireless service providers, we study competition between primary and secondary firms with this type of sharing, and characterize its ...

The Value of Sharing Intermittent Spectrum [PDF]
Management Science, 2020 We examine a model of Cournot competition with congestion motivated by recent policy to allow commercial sharing of wireless spectrum that is assigned to other users such as government agencies. A key feature of such spectrum is that it is intermittently available because of the incumbent user’s activity. In our model, wireless service providers (SPs)

Blockchain Based Spectrum Sharing
CoRR, 2023 Spectrum sharing has long been considered as method to improve spectrum resource utilization. Centralized geolocation database approach has been accepted globally for commercial applications. Recently blockchain has been considered as a platform to support spectrum sharing in a distributed manner.
