   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. On the Design of Noncoherent Acoustic Underwater Communication

   Author : Viktor Lidström; Magnus Lundberg Nordenvaad; Peter Sigray; Jacob Kuttenkeuler; Paul van Walree; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; noncoherent; acoustic underwater communication; link adaptation; adaptive networks; ickecoherent; akustisk undervattenskommunikation; länkadaption; adaptiva nätverk; Farkostteknik; Vehicle and Maritime Engineering;

   Abstract : The underwater domain is an environment hostile to humans due to the hydrostatic pressure that rapidly increases with water depth, which has led to underwater robotics becoming an emerging technological field with many commercial-, environmental-, and security-related applications. A major challenge to untethered autonomous underwater vehicles (AUVs) is communicating robot-to-robot and robot-to-topside operator since it must, in most cases, be done acoustically. READ MORE

7. 5. Towards a secure synchronous communication architecture for low-power wireless networks

   Author : Kasun Hewage; Thiemo Voigt; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

   Abstract : The Internet of Things (IoT) is becoming the future Internet where most day-to-day devices are connected to the Internet. These devices are often resource constrained and use low-power wireless communication. Hence networks of them are called low-power and lossy networks (LLNs). READ MORE
