Design Guidelines for Database-Driven Internet of Things-Enabled Dynamic Spectrum Access [PDF]

open access: yesSensors, 2021
The radio-frequency spectrum shortage, which is primarily caused by the fixed allocation policy, is one of the main bottlenecks to the deployment of existing wireless communication networks, and to the development of new ones. The dynamic spectrum access

Federated Dynamic Spectrum Access

open access: yesCoRR, 2021
Due to the growing volume of data traffic produced by the surge of Internet of Things (IoT) devices, the demand for radio spectrum resources is approaching their limitation defined by Federal Communications Commission (FCC). To this end, Dynamic Spectrum Access (DSA) is considered as a promising technology to handle this spectrum scarcity.

Enforcing dynamic spectrum access with spectrum permits [PDF]

open access: yesProceedings of the thirteenth ACM international symposium on Mobile Ad Hoc Networking and Computing, 2012
Given the flexibility of cognitive radio devices, a user can easily transmit on radio frequencies outside of her allocated range, creating harmful interference to legitimate transmissions. Therefore, how to effectively enforce allocated spectrum is a key challenge when deploying dynamic spectrum access in practice.

Towards Collaborative and Dynamic Spectrum Sharing via Interpretation of Spectrum Access Policies

open access: yesApplied Sciences, 2021
This paper describes some of the challenges that need to be addressed in order to develop collaborative spectrum-sharing systems. The importance of these challenges stems from the assumption that rules for spectrum sharing can change after the deployment

Modified Gini Index Detector for Cooperative Spectrum Sensing over Line-of-Sight Channels

open access: yesSensors, 2023
Recently, the Gini index detector (GID) has been proposed as an alternative for data-fusion cooperative spectrum sensing, being mostly suitable for channels with line-of-sight or dominant multi-path components.

COGNITIVE RADIOS FOR DYNAMIC SPECTRUM ACCESS - Polyphase Multipath Radio Circuits for Dynamic Spectrum Access [PDF]

open access: yesIEEE Communications Magazine, 2007
ABSTRACT Dynamic access of unused spectrum via a cognitive radio asks for flexible radio circuits that can work at an arbitrary radio frequency. This article reviews techniques to realize radios without resorting to frequency selective dedicated filters.

Application-aware dynamic spectrum access [PDF]

open access: yesWireless Networks, 2011
Dynamic Spectrum Access (DSA) allows unlicensed wireless devices to opportunistically access unoccupied licensed spectrum bands. DSA yields efficient spectrum utilization which can greatly improve wireless networking performance. In this paper, we advocate application-awareness to effectively manage the side-effects of DSA that can offset its benefits ...
