An Overview of Cognitive Radio Architecture a Review

Software-Defined Radio - Basics and Evolution to Cognitive Radio

We provide a brief overview over the development of software-defined or reconfigurable radio systems. The need for softwaredefined radios is underlined and the most important notions used for such reconfigurable transceivers are thoroughly defined. The role of standards in radio development is emphasized and the usage of transmission mode parameters in the construction of software-defined radio...

Spectrum Sensing Data Falsification Attack in Cognitive Radio Networks: An Analytical Model for Evaluation and Mitigation of Performance Degradation

Cognitive Radio (CR) networks enable dynamic spectrum access and can significantly improve spectral efficiency. Cooperative Spectrum Sensing (CSS) exploits the spatial diversity between CR users to increase sensing accuracy. However, in a realistic scenario, the trustworthy of CSS is vulnerable to Spectrum Sensing Data Falsification (SSDF) attack. In an SSDF attack, some malicious CR users deli...

Conceptualization of comorbid anxiety in autism spectrum disorder: An integrative literature review

Introduction: Anxiety is highly comorbid in children and adolescents with autism spectrum disorder (ASD), contributing to considerable impairments. In this account, the aim of study was to explore the explanations of anxiety in children and adolescents with ASD in relevant literature. Materials and Methods: This study is an integrative literature review and 3 electronic databases- Scopus, Scien...

Spectrum Assignment in Cognitive Radio Networks Using Fuzzy Logic Empowered Ants

The prevalent communications networks suffer from lack of spectrum and spectrum inefficiency. This has motivated researchers to develop cognitive radio (CR) as a smart and dynamic radio access promised solution. A major challenge to this new technology is how to make fair assignment of available spectrum to unlicensed users, particularly for smart grids communication. This paper introduces an i...
