Federated Dynamic Spectrum Access
CoRR, 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]
Proceedings 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.
