User-Centric Distributed Spectrum Sharing in Dynamic Network Architectures [PDF]
IEEE/ACM Transactions on Networking, 2019 We develop and analyze a new user-centric networking model for ubiquitous spectrum sharing where every user can share and use the spectrum under uncertainty of their traffic models. In this concept, users when connected to the Internet (wired/wireless) can dynamically serve as access points for other users in their vicinity.

Resource Distribution Approaches in Spectrum Sharing Systems
EURASIP Journal on Wireless Communications and Networking, 2008 It is increasingly difficult to satisfy growing demands for spectrum with the conventional policy of fixed spectrum allocation. To overcome this problem, flexible/dynamic spectrum sharing methods that can significantly improve spectrum utilization of the
