## 4 Review and Survey Articles
Only one article [5] dissected attacks such as call fraud and data interception in great detail. Several strategies, such as data encryption, mutual authentication, and other approaches can be used to address this issue. A study published in the article [6] examined the EDoS problem in emerging network situations. SON and NFV are the foundations for adaptive approaches. The author provided an overview of how multiple fog devices communicate with one another using Internet of Things paradigms. Describes these dangers and lays out future research on how to minimise the security concerns raised by a modern distributed control infrastructure [7]. Two articles [8; 9] comprehensively examine the use of machine learning approaches to significant 6G network concerns such as enhanced radio interface, intelligent traffic control, security protection, administration and orchestration, and network optimization. Furthermore, the latest status of important standardisation initiatives and industry research programmes on applying machine learning to mobile networks transitioning to 6G is examined. Only article [10] provided a full overview of AI-enabled 6G communication technology, which has a wide range of potential uses in the future. Examine how AI can be used in a variety of applications, including object localisation, UAV communication, surveillance, security, and privacy protection, among others. Finally, a use case was addressed that demonstrates the employment of AI principles in an intelligent transportation system. Only one article [11] was written about the current state of 6G security and privacy. The survey starts with a look back at earlier networking technologies and how they influenced contemporary 6G networking trends. Then, we'll go through four major components of 6G networks: real-time intelligent edge computing, distributed artificial intelligence, intelligent radio, and 3D intercoms, as well as some interesting upcoming technologies in each area, as well as the security and privacy challenges that come with them. Three papers [12; 13; 14] examined the major obstacles in integrating Blockchain and IoT technologies in order to achieve high-level solutions by addressing the weaknesses and limits of both technologies. Many IoT concerns can be addressed with blockchain, however, any merger of two embedded technologies brings additional issues and impediments. Second group: virtual and augmented reality virtualization Examine 5G and 6G approaches and categorise them into various types of solutions. Two studies [15; 16] reviewed virtualization solutions specifically developed for IoT networks, allowing users and operators to create environments that match their demands while coexisting with other networks in the same physical space.The article [17] looks at the characteristics of the fourth industrial revolution and considers 5G's potential as a GPT. Other researchers offered a new classification of recent fault management research accomplishments in network virtualization environments, as well as a comparison of their primary contributions and flaws [18]. \begin{table}
