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. Delay-sensitive wireless communication for cooperative driving applications

   Author : Annette Böhm; Magnus Jonsson; Elisabeth Uhlemann; Javier Gozalvéz; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative driving applications; wireless communication;

   Abstract : Cooperative driving holds the potential to considerably improve the level of safety and efficiency on our roads. Recent advances in in-vehicle sensing and wireless communication technology have paved the way for the development of cooperative traffic safety applications based on the exchange of data between vehicles (or between vehicles and road side units) over a wireless link.

   Abstract : The work at hand is a selection of topics in efficient wireless communication system design, with topics logically divided into two groups.One group can be described as hardware designs conscious of their possibilities and limitations. READ MORE

6. 4. 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

7. 5. Using Existing Infrastructure as Support for Wireless Sensor Networks

   Author : Jonas Neander; Mats Björkman; Mikael Nolin; Jukka Mäki-Turja; Björn Knutsson; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wireless; sensor networks; communication; base station; asymmetric communication; multihop; network lifetime; Computer science; Datavetenskap; Datavetenskap;

   Abstract : Denna avhandling handlar om hur befintliga datorinfrastrukturer i t.ex. sjukhus och industrier kan avlasta sensornätverk med energikrävande uppgifter. Vi har forskat på olika aspekter som gör det möjligt att förlänga livslängden på dessa sensornätverk. READ MORE
