Security and Enforcement in Spectrum Sharing
Proceedings of the IEEE, 2014When different stakeholders share a common resource, such as the case in spectrum sharing, security and enforcement become critical considerations that affect the welfare of all stakeholders. Recent advances in radio spectrum access technologies, such as cognitive radios, have made spectrum sharing a viable option for significantly improving spectrum ...

Auction-Based Spectrum Sharing
Mobile Networks and Applications, 2006We study auction mechanisms for sharing spectrum among a group of users, subject to a constraint on the interference temperature at a measurement point. The users access the channel using spread spectrum signaling and so interfere with each other. Each user receives a utility that is a function of the received signal-to-interference plus noise ratio ...

Accelerating Spectrum sharing technologies
IEEE Communications Magazine, 2013Spectrum sharing potentially holds the promise of solving the emerging spectrum crisis. However, technology innovators face the conundrum of developing spectrum sharing technologies without the ability to experiment and test with real incumbent systems.

Competition and investment in shared spectrum
2015 49th Asilomar Conference on Signals, Systems and Computers, 2015Meeting the exploding demand for wireless data services will require access to new wireless spectrum. However, the traditional approach of clearing spectrum and reallocating it is becoming increasingly difficult. This in turn has led to much interest in new approaches for sharing spectrum among different users, such as the those being currently ...

Spectrum Sharing for Drone Networks
IEEE Journal on Selected Areas in Communications, 2016In this paper, we study spectrum sharing of drone small cells (DSCs) network modeled by the 3-D Poisson point process. This paper also investigates an underlay spectrum sharing between the 3-D DSCs network and traditional cellular networks modeled by 2-D Poisson point processes.

Shared Spectrum Allocation via Pathloss Estimation in Crowdsensed Shared Spectrum Systems
2019 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2019The RF spectrum is a natural resource in great demand. The research community has addressed this unabated increase in demand via development of shared spectrum paradigms, wherein the spectrum is made available to unlicensed users (secondaries) as long as they do not interfere with the transmission of licensed incumbents (primaries).

Spectrum Sharing Through Beacons
2005 IEEE 16th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006Recently there has been considerable interest in the sharing of spectrum between different services in order to maximize its utilization. This paper presents a novel concept for the sharing of spectrum based on arranging for the receivers to transmit beacons that establish a soft exclusion zone for other transmitters to avoid interference.
