  1. 1. Challenged Networking : An Experimental Study of new Protocols and Architectures

    Författare :Erik Nordström; Per Gunningberg; Brian Levine; Uppsala universitet; []
    Nyckelord :Challenged networking; Network Architecture; Wireless Ad hoc Networks; Delay Tolerant Networks; Opportunistic Networks; Testbeds.;

    Sammanfattning : With the growth of Internet, the underlying protocols are increasingly challenged by new technologies and applications. The original Internet protocols were, however, not designed for wireless communication, mobility, long disconnection times, and varying bandwidths. LÄS MER

  3. 2. Algorithms and Proofs of Concept for Massive MIMO Systems

    Författare :Joao Vieira; Kommunikationsteknologi; []
    Nyckelord :massive MIMO; Algorithms; Testbeds; Deep Learning; Generalized Method of Moments;

    Sammanfattning : This thesis focuses on algorithms and proofs of concepts in the area of wireless systems operating with a large number of antennas, especially at the base station side.The first studied topic concerns the design and implementation of massive multiple-input multiple-output (MIMO) testbeds, primarily for communications.

  4. 3. Sensor Networks and Their Radio Environment : On Testbeds, Interference, and Broken Packets

    Författare :Frederik Hermans; Per Gunningberg; Edith Ngai; Andreas Terzis; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; Testbed; Mobility; Interference classification; Packet corruption; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Sensor networks consist of small sensing devices that collaboratively fulfill a sensing task, such as monitoring the soil in an agricultural field or measuring vital signs in a marathon runner. To avoid cumbersome and expensive cabling, nodes in a sensor network are powered by batteries and communicate wirelessly. LÄS MER

  5. 4. Improving the Adaptability of the End-host : Service-aware Network Stack Tuning

    Författare :Alexander Rabitsch; Anna Brunström; Per Hurtig; Stefan Alfredsson; Michael Welzl; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transport layer; 5G; transport services; mobile broadband; network slicing; latency; availability; service optimization; multi-connectivity; Computer Science; Datavetenskap;

    Sammanfattning : The Internet of today is very different from how it used to be. Modern networked applications are becoming increasingly diverse. Consequently, a variety of requirements must be met by the network. Efforts to make the underlying mechanisms of the Internet more flexible have therefore been made to adapt to this diversification.

  7. 5. Identification of Cyberattacks in Industrial Control Systems

    Författare :Alireza Dehlaghi-Ghadim; Hans Hansson; Ali Balador; Mahshid Helali Moghadam; Mohammad Shojafar; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : As critical infrastructure increasingly relies on Industrial Control Systems (ICS), these systems have become a prime target for cyberattacks. As a result of the move towards Industry 4.0 targets, ICSs are increasingly being connected to the outside world, which makes them even more vulnerable to attacks. LÄS MER
