Spectrum Sharing Between Wireless Networks [PDF]

open access: yesIEEE INFOCOM 2008 - The 27th Conference on Computer Communications, 2008
We consider the problem of two wireless networks operating on the same (presumably unlicensed) frequency band. Pairs within a given network cooperate to schedule transmissions, but between networks there is competition for spectrum. To make the problem tractable, we assume transmissions are scheduled according to a random access protocol where each ...

Building trust via blockchain in UAV‐assisted ultra‐dense 6G cellular networks

open access: yesIET Blockchain, 2022
The ultra‐dense deployment of unmanned aerial vehicles (UAVs) as mobile small cell base stations (SBS) is expected to support ultra‐high‐speed, ultra‐reliable, and ultra‐low‐latency wireless connections in sixth generation (6G) wireless cellular networks.

Database-Assisted Distributed Spectrum Sharing [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2013
According to FCC's ruling for white-space spectrum access, white-space devices are required to query a database to determine the spectrum availability. In this paper, we study the database-assisted distributed white-space access point (AP) network design. We first model the cooperative and non-cooperative channel selection problems among the APs as the

Imitation-Based Social Spectrum Sharing [PDF]

open access: yesIEEE Transactions on Mobile Computing, 2015
Dynamic spectrum sharing is a promising technology for improving the spectrum utilization. In this paper, we study how secondary users can share the spectrum in a distributed fashion based on social imitations. The imitation-based mechanism leverages the social intelligence of the secondary user crowd and only requires a low computational power for ...

A Consensus-Based Protocol for Spectrum Sharing Fairness in Cognitive Radio Ad Hoc and Sensor Networks

open access: yesInternational 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 ...
