Sixth Generation (6G) Cognitive Radio Network (CRN) Application, Requirements, Security Issues, and Key Challenges

Abstract

Recently, 5G installation has been started globally. Different capabilities are in the consistent procedure, like ultrareliability, mass connectivity, and specific low latency. Though, 5G is insufficient to meet all the necessities of the future technology in 2030 and so on. Next generation information and communication technology is playing an important role in attraction of researchers, industries, and technical people. With respect to 5G networks, sixth-generation (6G) CR networks are anticipated to familiarize innovative use cases and performance metrics, such as to offer worldwide coverage, cost efficiency, enhanced spectral, energy improved intelligence, and safety. To reach such requirements, upcoming 6G CRNs will trust novel empowering technologies. Innovative network architecture and transmission technologies and air interface are of excessive position, like multiple accesses, waveform design, multiantenna technologies, and channel coding schemes. (1) To content, the condition should be of worldwide coverage, there will be no limit on 6G to global CR communication networks that may require to be completed with broadcast networks, like satellite communication networks, therefore, attaining a sea integrated communication network. (2) The spectrums overall will be entirely travelled to the supplementary rise connection density data rates in optical frequency bands, millimeter wave (mmWave), sub-6 GHz, and terahertz (THz). (3) To see big datasets created because of tremendously varied CR communication networks, antenna rush, diverse communication scenarios, new provision necessities, wide bandwidth, and 6G CRNs will allow an innovative variety of intelligent applications with the assistance of big data and AI technologies. (4) Need to improve network security when deploying 6G technology in CR networks. 6G is decentralized, intended, intelligent innovative, and distributed network. In this article, we studied a survey of current developments and upcoming trends. We studied the predicted applications, possible technologies, and security issues for 6G CR network communication. We also discussed predicted future key challenges in 6G.

An Overview of Recent Advances of Resilient Consensus for Multiagent Systems under Attacks

“…An algorithm is discussed for the detection of deception attack in an application which could be remote state application, smart sensors used for data receiving [105]. Second application of such kind has been studied for the detection of bias injection attacks for stochastic rectilinear dynamical scheme [12,[106][107][108][109]. Multiclass support vector machine was discussed for building an intrusion detection model.…”

“…Approach. GT deals with planned collaboration in between several named players and decision makes [107,140,141]. Each player preference order in between many options is increased in an impartial purpose for player, and all players try to optimize own impartial function.…”

“…e Kalman filter method is not enough for MASs, and it is difficult to gain attacker in statically characterization of signal transmitted [107,171]. In research studies, interest control problem and filtering in concern of security are getting more and attention, e.g., [79] in which there assurance of security against integrity attacks with the use of minimax optimization advancement [167].…”

“…Aslam et al studied a survey of current developments and upcoming trends. 13 They also studied the predicted applications, possible technologies, and security issues for 6G CR network communication. Salahdine and Kaabouch described and analyzed different attacks targeting the physical layer.…”

“…In their research, after secondary users are identified by the primary user to access the primary network, the secondary users are given the authorization to access the primary network. Aslam et al studied a survey of current developments and upcoming trends 13 . They also studied the predicted applications, possible technologies, and security issues for 6G CR network communication.…”
