Jesus’ Methods of Communication and Its Implications for Nigerian Pastors.
(International Journal of Biblical & Cognate Studies (IJBCS): Benue State University, 2020) Peter Olanrewaju Awojobi
Good communication is key to sound organizational practice and successful group relationship. Leaders are expected to give accurate and clear information to their followers. The leadership is to provide clear, accurate facts and figures so that their followers can effectively complete their tasks. This paper examined Jesus’ methods of Communication and its Implications for Pastors in Nigeria. The study through the use of Historical method discovered that methods used by Jesus were not strange to his audience. Jesus’ audience had a good understanding of what he was trying to communicate to them because he spoke in clear terms and in the language they understood. Nigerian is in need of leaders like Jesus that will communicate divine message clearly and boldly.

History of security and privacy in wireless communication systems: open research issues and future directions
(2023) Musa, Abdulwaheed
Wireless communication is one of the most successful technologies that have found application in various sectors of our daily lives. However, one of the major issues and challenges of wireless communication is security. To provide a holistic view of this crucial issue, this chapter presents a historical description of the evolution of the cellular network and provides a general overview of different attacks and vulnerabilities in the wireless network based on the Open System Interconnection (OSI) layered protocol architecture. The chapter further presents a brief review of the security and privacy issues for each cellular generation. The various emerging wireless communication systems as well as the application of artificial intelligence (AI) and machine learning (ML) to wireless security system design. The security issues and challenges in the key technology of 6G wireless network were identified and discussed. Finally, open research issues have been identified and discussed, giving a path for further research direction for security in 5G wireless networks and beyond.

Legal frameworks for security schemes in wireless communication systems
(2023) Musa, Abdulwaheed
Wireless communication is one of the very successful technologies that have found applications in our daily lives. It has drawn the attention of researchers, standard bodies, and organizations who have continuously proposed and developed different standards and regulations to further advance the communication system. However, one of the major issues and concerns that have been raised in wireless communication is security with its legal frameworks. Security as well as privacy are very crucial schemes in wireless communication because of the transmission of signals over unprotected media, thus exposing signals to security and privacy attacks such as eavesdropping, modification, and data theft, among others. Depending on the type of data being transmitted, security and privacy and the legal frameworks become even more critical, especially with the adoption of new technology such as cloud computing in the healthcare and other sectors. While framework is a structure that combines, in the form of a single hybrid conceptual solution, different but relevant areas together, the legal frameworks are simply a set of standards which can be utilized to deal with a challenge or to decide what to do. Some legal frameworks have been developed, over the years, particularly in the area of healthcare, Artificial Intelligence (AI) and Internet of Things (IoT). However, there are no sufficient legal frameworks for the security and privacy of wireless network, particularly for the envisioned 6G network. Thus, this chapter presents the fundamental factors of legal frameworks for the security and privacy in a wireless communication network with a focus on the 6G network.

Implementation of Intelligent Fuzzy Logic Scheme in Video Transmission Over 2.4 GHz Wireless
(2018) Musa, Abdulwaheed
Video transmission over varying channels like wireless technology is unpredictable because of interferences caused by other wireless devices in the same Industrial, Scientific and Medicine (ISM) frequency band and/or general channel noises. Transmitting Moving Picture Expert Group (MPEG) video stream over wireless technology presents a challenge, as MPEG demands large bandwidth. Considering these issues of interference and bandwidth consumption, an intelligent transmission is introduced in this research work such that the controller adjusts itself to the current state of the wireless channel to sustain MPEG video quality during the communication process. A neural-fuzzy controller and a rule-based fuzzy controller are implemented in the design to monitor input - output of a traffic shaping buffer and offer suitable parameters for the MPEG encoder for video transmission over the network. This method reduces data loss and improves image quality as compared to traditional open-loop MPEG video transmission over wireless.

5G Frequencies Standardization, Technologies, Channel Models and Network Deployment: Advances, Challenges, and Future Directions
(2023) Musa, Abdulwaheed
The rapid increase in data traffic caused by the proliferation of smart devices has spurred the demand for extremely large-capacity wireless networks. Thus, faster data transmission rates and greater spectral efficiency have become critical requirements in modern-day networks. The ubiquitous 5G is an end-to-end network capable of accommodating billions of linked devices and offering high-performance broadcast services due to its several enabling technologies. However, the existing review works on 5G wireless systems examined only a subset of these enabling technologies by providing a limited coverage of the system model, performance analysis, technology advancements, and critical design issues, thus requiring further research directions. In order to fill this gap and fully grasp the potential of 5G, this study comprehensively examines various aspects of 5G technology. Specifically, a systematic and all-encompassing evaluation of the candidate 5G enabling technologies was conducted. The evolution of 5G, the progression of wireless mobile networks, potential use cases, channel models, applications, frequency standardization, key research issues, and prospects are discussed extensively. Key findings from the elaborate review reveal that these enabling technologies are critical to developing robust, flexible, dependable, and scalable 5G and future wireless communication systems. Overall, this review is useful as a resource for wireless communication researchers and specialists.
