  1. 21. Security in low power wireless networks : Evaluating and mitigating routing attacks in a reactive, on demand ad-hoc routing protocol

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Tony Fredriksson; Niklas Ljungberg; [2017]
    Nyckelord :IoT; Security; Ad-hoc Routing; RIME; Sinkhole; Selective Forwarding; Sybil; Intrusion Detection System;

    Sammanfattning : Using low energy devices to communicate over the air presents many challenges to reach security as resources in the world of Internet Of Things (IoT) are limited. Any extra overhead of computing or radio transmissions that extra security might add affects cost of both increased computing time and energy consumption which are all scarce resources in IoT.

  3. 22. Real-time Coding for Kinesthetic and Tactile Signals

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Liyang Zhang; [2016]
    Nyckelord :;

    Sammanfattning : The Tactile Internet is at the core of the 5G era, when the world will experience paradigm shift from content-delivery networks to service/labour-delivery ones. Systems that enable wireless communications of haptic data feature bi-directionality, high packet rate and resolution, large degrees of freedom, and above all, strict latency requirements in many applications, aggravating the shortage of wireless resources.

  4. 23. A Space-Time Study of the Electron-Electron Interaction in High-TC Parent Compound La2CuO4: In Search of an Attractive Effective Interaction

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Tor Sjöstrand; [2016]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The superconductivity under doping in the famous cuprate compounds is believed to originate in the CuO2 planes. The mediator of pairing is generally accepted to be induced from electronic degrees of freedom. LÄS MER

  5. 24. Real-Time Lossless Compression of SoC Trace Data

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Jing Zhang; [2015]
    Nyckelord :Compression; Nexus Trace Data; Technology and Engineering;

    Sammanfattning : Nowadays, with the increasing complexity of System-on-Chip (SoC), traditional debugging approaches are not enough in multi-core architecture systems. Hardware tracing becomes necessary for performance analysis in these systems. LÄS MER

  7. 25. Delta encoding image archives : Comparing delta encoding and PNG as compression methods for image archives

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Isak Jägberg; Mats Stichel; [2015]
    Nyckelord :;

    Sammanfattning : This thesis studies the effect of using delta encoding to compress archivesof images. The results are compared with two types of lossless PNGcompression. The tests show that the most sophisticated PNG methodtested compresses the archives around 2-12% higher than the delta encodingmethods, but at the cost of taking more than 10 times as long. LÄS MER
