  1. 1. Battery-free Visible Light Sensing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för datorteknik

    Författare :Andreas Soleiman; [2019]
    Nyckelord :Networked embedded systems; Visible light sensing; RF backscatter; Energy harvesting;

    Sammanfattning : In this thesis, we show that it is possible to design a battery-free light sensing system that can sense and communicate hand gestures while operating fully on harvested power from indoor light. We present two main innovations that push our system to tens of microwatts of power to enable battery-free operation. LÄS MER

  2. 2. Energy-Efficient Communication with Lightweight M2M in IoT Networks

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Gonzalo Peces; [2018]
    Nyckelord :IoT; LwM2M; low power consumption; TSCH; Contiki-NG; Eclipse Leshan.; IoT; LwM2M; låg energiförbrukning; TSCH; Contiki-NG; Eclipse Leshan.;

    Sammanfattning : OMA’s Lightweight Machine to Machine (LwM2M) is an application protocol for device management in the Internet of Things (IoT) that has been recently published and widely adopted in a lot of projects. The protocol is designed to operate in sensor networks and machine-to-machine environments, where one of the main constraints is the energy consumption since the nodes are usually battery powered.

  3. 3. RISKS AND CONSEQUENCES OF CYBER- ATTACKS AFFECTING DSO'S AND ELECTRICAL SUPPLIER’S BUSINESS PROCESSES IN THE SUPPLIER CENTRIC MODEL

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

    Författare :Rodrigo Gonzalez Hernandez; [2016]
    Nyckelord :Data service hub; Process resilience; Supplier Centric Model; Business Process hacking; Cyber-Security and Nordic Electricity Retail Market; Tjänstehubb; Process spänstighet; Elleverantörs Centriska Modellen; Process hackning; Cyber-Säkerhet och Nordiska elmarknaden;

    Sammanfattning : There has been a motivated desire from different power system operators to have more systems embedded in computing and networking due to the great advantages of adding new capabilities that wasn't before possible. These advantages increased the power system’s up-time, performance and reduced its maintenance but opened a world of possible cyber-attacks. LÄS MER

  4. 4. Security concerns regarding connected embedded systems

    Master-uppsats, Linköpings universitet/Databas och informationsteknikLinköpings universitet/Tekniska högskolan

    Författare :Jon Mårdsjö; [2013]
    Nyckelord :Embedded security; network security; risk management; untrusted domains; interconnected systems; Internet of Things IoT .;

    Sammanfattning : Embedded systems have been present in our daily lives for some time, but trends clearly show a rise in inter-connectivity in such devices. This presents promising new applications and possibilities, but also opens up a lot attack surface. LÄS MER

  5. 5. Data Processing Algorithms in Wireless Sensor Networks får Structural Health Monitoring

    Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Författare :Nigatu Mitiku Danna; Esayas Getachew Mekonnen; [2012]
    Nyckelord :Bridge; FFT; Modal Analysis; Monitoring; Natural Frequency; Peak Picking; Structure; Wireless Sensor.;

    Sammanfattning : The gradual deterioration and failure of old buildings, bridges and other civil engineering structures invoked the need for Structural Health Monitoring (SHM) systems to develop a means to monitor the health of structures. Dozens of sensing, processing and monitoring mechanisms have been implemented and widely deployed with wired sensors. LÄS MER
