Journal ArticleDOI
A Survey on Security Threats and Detection Techniques in Cognitive Radio Networks
TL;DR: The scope of this work is to give an overview of the security threats and challenges that cognitive radios and cognitive radio networks face, along with the current state-of-the-art to detect the corresponding attacks.
Journal ArticleDOI
Spectrum Assignment in Cognitive Radio Networks: A Comprehensive Survey
TL;DR: The scope of this work is to give an overview of the problem of spectrum assignment in cognitive radio networks, presenting the state-of-the-art proposals that have appeared in the literature, analyzing the criteria for selecting the most suitable portion of the spectrum and showing the most common approaches and techniques used to solve the spectrum assignment problem.

TL;DR: This work presents four applications that will be developed within RERUM, gives a general description of the open reliability and security issues that have to be taken into account and gives an overall view of the solutions that RERum will develop to address these issues.
Journal ArticleDOI
Anomaly-based intrusion detection of jamming attacks, local versus collaborative detection
TL;DR: This work compares the performance of local algorithms on the basis of the signal-to-interference-plus-noise ratio SINR executing independently at several monitors, with a collaborative detection algorithm that fuses the outputs provided by these algorithms with the Dempster-Shafer theory of evidence algorithm.
Journal ArticleDOI
Ubiquitous robust communications for emergency response using multi-operator heterogeneous networks
TL;DR: A flexible network architecture that provides a common networking platform for heterogeneous multi-operator networks, for interoperation in case of emergencies is proposed and several schemes that can be adopted by the proposed architecture are suggested to meet those requirements.
