    Fog computing power for telepresence suit as user terminal for Metaverse
    (Faculty of Engineering, 2026-01) Mogilatov, V; Kaijalainen, V; Volkov, A; Muthanna, A; Koucheryavy, A.
    Fog computing represents an emerging paradigm in information and communication technologies that is becoming pivotal for meeting the growing performance requirements of modern computing systems, particularly in the context of the Internet of Things (IoT) and real-time services. One of the most promising 2030-network service classes enabled by fog is telepresence. This paper investigates both the theoretical and practical aspects of deploying fog-computing solutions in telepresence networks to minimize latency and enhance overall system performance. The study combines analytical modelling with discrete-event simulations carried out in Any Logic.

    Analysis and optimization of OLSR and AODV routing protocols for highly mobile autonomous aerial vehicle networks: experimental performance evaluation in various application scenarios
    (Faculty of Engineering, 2026-01) Duc Tu, N; Gorbacheva, L; Muthanna, A
    Driven by the rapid evolution of Autonomous Aerial Vehicle (AAV) technology, ad-hoc AAV networks are becoming increasingly significant in diverse domains such as telecommunications, security surveillance, search-and-rescue operations, emergency management, precision agriculture, and cargo transportation. Owing to their flexible deployment and tight coordination capabilities, AAVs enable real-time data exchange, unlocking considerable potential for tasks that demand high accuracy and swift response. Nevertheless, their three-dimensional mobility and continuously changing topology impose substantial challenges on the design of suitable routing solutions, because conventional protocols originally developed for Mobile Ad-hoc Networks (MANETs) are seldom optimized for aerial characteristics. This discrepancy underscores the necessity for a comprehensive analysis and optimal configuration that satisfy the stringent requirements of low latency, high throughput, and reliability in mission-critical AAV applications. Against this backdrop, the present study focuses on the analysis and modelling of two widely adopted routing protocols—Optimized Link State Routing (OLSR) and Ad hoc On-Demand Distance Vector (AODV)—in various deployment contexts of ad-hoc AAV networks. By evaluating the performance of these protocols, we identify their advantages, limitations, and possible enhancement directions, and subsequently propose configuration guidelines that deliver improved link quality.

    ADOPTION OF A CIRCULAR ECONOMY FRAMEWORK IN THE DESIGN PHASE OF THE REFURBISHMENT PROJECT
    (Faculty of Engineering, 2026-01) Abilash, S; Gunarathna, K A N; Kalugala,C.
    Sustainable development in the built environment depends on minimizing environmental impact and conserving resources. In refurbishment projects, integrating circular economy (CE) principles during the design stage can significantly reduce waste and enhance resource efficiency. This study presents a tailored CE framework based on the 2D3R model, which emphasizes Design for Disassembly, Design for Adaptability, and Reduce, Reuse, and Recycle strategies. The framework was developed through a combination of literature review, expert interviews, and survey analysis to identify drivers and barriers to CE adoption in refurbishment. Key findings highlight the role of digital technologies particularly Building Information Modelling (BIM) in improving material traceability and facilitating lifecycle assessments. These tools support the implementation of circular strategies by enabling better planning and design decisions early in the project. The study concludes that applying the 2D3R approach in initial design phases enhances sustainability, reduces costs, and improves the adaptability and longevity of refurbished buildings.
