  2. 1. Towards Secure Synchronous Communication Architectures for Wireless Networks

    Author : Kasun Hewage; Thiemo Voigt; Shahid Raza; Matthias Hollick; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datagram Transport Layer Security; Synchronous Transmissions; Denial-of-service Attacks; Transmission Control Protocol; Communication Security; Time Synchronisation; Optical Wireless Communication; Networked Embedded Systems; Internet of Things; Electrical Engineering with Specialisation in Networked Embedded Systems; Elektroteknik med inriktning mot nätverksbaserade inbyggda system;

    Abstract : The vision behind the Internet of Things (IoT) revolves around creating a connected ecosystem where devices, people, and systems collaborate seamlessly, unlocking new possibilities, improving efficiency, and enhancing our daily lives. IoT encloses many device classes, including low-power wireless devices that rely on batteries or energy harvesting. READ MORE

  4. 2. Energy Constrained Wireless Sensor Networks : Communication Principles and Sensing Aspects

    Author : Erik Björnemo; Anders Ahlén; Mikael Sternad; Erik Larsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; Signal processing; Signalbehandling;

    Abstract : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. READ MORE

  5. 3. RF Wireless Power Transfer for IoT Applications

    Author : Morteza Tavana; Emil Björnson; Jens Zander; Ayça Özçelikkale; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic waste; Energy harvesting; Internet of things; transceivers; wireless power transfer; wireless sensor networks; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : With the emergence of the Internet of things (IoT) networks, the replacement of batteries for IoT devices became challenging. In particular, the battery replacement is more expensive and cumbersome for scenarios where there are many IoT devices; or where the IoT devices are in unreachable locations; or when they have to be replaced often.
