Dynamic Spectrum Sharing Models for Cognitive Radio Aided Ad Hoc Networks and Their Performance Analysis [PDF]
, 2011 In this paper, two dynamic spectrum sharing models are proposed, namely a Markov-chain model and a queue-based model in order, to evaluate the performance of CRAHNs, where the shared Primary Channels (PCs) are complemented by unshared Secondary Channels (

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.

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)
