  1. 21. Net-based Learning and the mStar Environment

    Författare :Kåre Synnes; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Sammanfattning : This licentiate thesis focuses on how to design a robust and flexible environment for net-based learning. The environment is required to be scalable for large groups, robust over lossy networks, flexible to meet different learning scenarios, and support interactivity. LÄS MER

  3. 22. Network and user-level traffic adaptation for collaborative-workspace applications

    Författare :Jeremiah Scholl; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : Collaborative workspace applications based on IP-multicast offer a scalable solution for computer supported human-to-human communication. Although Internet-wide multicast access is not a reality, multicast deployment is steadily increasing on subnets, such as corporate and campus networks. LÄS MER

  4. 23. Application semantics for cost-effective media distribution

    Författare :Stefan Elf; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Sammanfattning : Public use of the Internet increases as wideband connections become pervasive and applications suitable for media distribution grow popular. Group collaboration applications have attracted interest during recent years. Wireless connectivity and business applications also furthers a need for reliable communication protocols. LÄS MER

  5. 24. Large scale and mobile group communication systems

    Författare :Roland Parviainen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Sammanfattning : This doctoral thesis examines different attributes of large scale group communication systems such as scalability, security and mobility by studying two different prototype systems - mIR (multicast Interactive Radio) and MES (Mobile E-meeting Services). mIR is a system for large scale real-time music distribution, designed as an interactive radio system for the Internet.

  7. 25. Towards SDN/NFV-based Mobile Packet Core : Benefits, Challenges, and Potential Solutions

    Författare :Van-Giang Nguyen; Anna Brunström; Karl-Johan Grinnemo; Javid Taheri; Kurt Tutschku; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile packet core; evolved packet core; SDN; NFV; 5G; scalability; load balancing; control plane; open5Gcore; Computer Science; Datavetenskap;

    Sammanfattning : In mobile networks, the mobile core plays a crucial role in providing connectivity between mobile user devices and external packet data networks such as the Internet. Through the years, along with the dramatical changes in radio access networks, the mobile core has also been evolved from being a circuit-based analog telephony system in its first generation (1G) to become a purely packet-based network called the Evolved Packet Core (EPC) in the current generation (4G).
