  1. 16. Simulation-based development of distributed control systems in energy-efficient data centres

    Författare :Yulia Berezovskaya; Valeriy Vyatkin; Chen-Wei Yang; Lena Wosinska; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : The main focus of this thesis is on the area of integrated automated control systems inmodern data centres. The data centres are mission-critical facilities since they provide services for transporting, storing and processing vast amounts of data, which can be considered the ”new oil” of the Industry 4.0 era.

  3. 17. Methodologies and Practical Tools for Realistic Large Scale Simulations of Wireless Sensor Networks

    Författare :Laurynas Riliskis; Philip Levis; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : Wireless Sensor Networks (WSNs) have evolved into large and complex systems and are now one of the major technologies used in Cyber-Physical Systems (CPS) and the Internet of Things (IoT).Extensive research on WSNs has led to the development of diverse solutions for all layers of software architecture, including protocol stacks for communications.

  4. 18. Data structures for bandwidth reservations and quality of service on the Internet

    Författare :Andreas Nilsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : This thesis deals firstly with ways to solve the problem of limited resource reservations over time, and secondly, handling conforming traffic in routers. At first glance these topics seem a bit unrelated, they are both related to quality of service (QoS) on the Internet and are cases of Algorithm Engineering applied in the field of Computer Networking.

  5. 19. TCP/IP technology for modern network environments

    Författare :Sara Landström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : To facilitate the merging of wireless access technologies and the traditional Internet, the core protocols for data communication should be robust and have low overhead. In this thesis, we propose refinements to the Transmission Control Protocol (TCP) that improve its cost efficiency over wireless links. LÄS MER

  7. 20. Quality issues in Internet packet forwarding

    Författare :Ulf Bodin; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : This thesis addresses quality issues in Internet Protocol (IP) packet forwarding. In IP networks, queue mechanisms and scheduling can be used to construct multiple forwarding behaviors. Thereby, both relative and independent services can be offered to Internet users. Independent services offer forwarding qualities known beforehand. LÄS MER
