Produktbeschreibung
Scientific Study from the year 2025 in the subject Computer Science - Commercial Information Technology, grade: Excellent, Mekelle University (Ethiopian civil aviation authority), course: computer science, language: English, abstract: The rapid proliferation of mobile and ubiquitous systems has fundamentally transformed how people engage with digital services-enabling real-time interactions across diverse environments and ever-changing contexts. Characterized by continuous availability, seamless integration, and deep context-awareness, these systems bring unique challenges spanning performance, usability, security, and scalability. Evaluating them demands a holistic set of metrics that not only capture technical efficiency but also human-centered factors such as user satisfaction and adaptability. This paper presents a comprehensive framework of metrics and testing methodologies tailored for mobile and ubiquitous systems. It covers critical dimensions including performance, energy efficiency, usability, context-awareness, and security, while emphasizing the role of simulation tools, real-world testing, and user feedback in crafting resilient and trustworthy technologies. As these technologies become woven into the fabric of smart cities, healthcare, transportation, and disaster response, this research lays the foundation for future innovations that harmonize technical excellence with empathy and inclusiveness-empowering mobile and ubiquitous systems to be not just smart, but truly human-centric and reliable. It can be used by: 1. Researchers and Academics 2. System Designers and Engineers 3. Mobile App and Software Developers 4. ICT Industry Professionals and QA Engineers 5. IoT and Ubiquitous System Providers 6. Policy Makers and Standards Bodies as a reference
Autorenporträt
Kahsay Kiross Meresa received his B.Sc. in Electrical Engineering and M.Sc. in Communication Engineering from Mekelle University, Ethiopia. During his undergraduate studies, he built a strong foundation in electrical circuits, electronics, signal processing, and communication systems, which fostered his interest in wireless and mobile technologies. His graduate studies expanded this expertise, focusing on LTE downlink systems, channel estimation, antenna theory, and wireless system design. His M.Sc. thesis investigated pilot-based, LS, MMSE, and adaptive filtering techniques to enhance throughput, reliability, and spectral efficiency in LTE networks, providing insights into physical layer optimization under real-world conditions. Kahsay's research spans four main areas: channel estimation for LTE downlink systems, physical layer modeling and network optimization, evaluation of mobile and ubiquitous systems, and ICT applications for humanitarian assistance. He has studied MIMO diversity schemes, resource allocation, energy-efficient network design, and performance metrics for mobile systems. His work emphasizes practical deployment, particularly in regions with constrained infrastructure. A distinctive aspect of his research explores ICT solutions for post-conflict reconstruction, including digital identity systems, telemedicine, mobile money platforms, and satellite-based monitoring. This interdisciplinary approach positions him at the intersection of engineering innovation and social impact, demonstrating how technology can support governance, humanitarian logistics, and community resilience. His professional experience includes roles as an Electrical and Electronics Engineer, Navigation Aids and CNS Engineer, CNS Engineer III, and ICT specialist in the Peace and Security Office (Tigray), contributing to digital ID implementations and infrastructure planning. Kahsay's publications include Channel Estimation Techniques for LTE Downlink Systems, Metrics and Measures for Evaluating Mobile and Ubiquitous Systems, Digital Identity Systems in Tigray, and ICTs in Post-Conflict Humanitarian Assistance. Looking forward, he aims to advance LTE/5G/6G systems, energy-efficient wireless networks, AI-driven channel estimation, federated learning for distributed networks, and secure digital identity platforms to foster inclusive development and post-conflict recovery.
