SpecGuard: Spectrum misuse detection in dynamic spectrum access systems

2015 IEEE Conference on Computer Communications (INFOCOM), 2015
Dynamic spectrum access is the key to solving worldwide spectrum shortage. The open wireless medium subjects DSA systems to unauthorized spectrum use by illegitimate users. This paper presents SpecGuard, the first crowdsourced spectrum misuse detection framework for DSA systems.

Performance enhancement of steady-state Markov analysis for cognitive radio networks via channel reservation

Alexandria Engineering Journal, 2017
Cognitive radio wireless networks CRNs have been considered as an efficient communication paradigm to the utilization of scarce spectrum. The main purpose of channel reservation of dynamic spectrum access (DSA) is to access these idle channels ...
