  1. 16. Towards a secure synchronous communication architecture for low-power wireless networks

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

    Sammanfattning : 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). LÄS MER

  3. 17. Public Key Infrastructure and its applications for resource-constrained IoT

    Författare :Joel Höglund; Shahid Raza; Thiemo Voigt; Andrei Gurtov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IoT; PKI; cybersecurity; security; asymmetric cryptography; Contiki-NG; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : The Internet of Things (IoT) is rapidly expanding and IoT devices are being deployed in security-critical scenarios, such as in critical infrastructure monitoring and within e-health, and privacy-sensitive applications in hospitals and homes. With this, questions of security and safety become paramount. LÄS MER

  4. 18. Implementation and real-world evaluation of routing protocols for wireless ad hoc networks

    Författare :Henrik Lundgren; Per Gunningberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. To enable communication between nodes that do not have direct radio contact, each node must function as a wireless router and potentially forward data traffic on behalf of the others. LÄS MER

  5. 19. Robustness in low power wide area networks

    Författare :Charalampos Orfanidis; Martin Jacobsson; Per Gunningberg; Matti Hämäläinen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : During the past few years we have witnessed an emergence of Wide Area Networks in the Internet of Things area. There are several new technologies like LoRa, Wi-SUN, Sigfox, that offer long range communication and low power for low-bitrate applications. LÄS MER

  7. 20. Enabling Sustainable Networked Embedded Systems

    Författare :Ambuj Varshney; Thiemo Voigt; Luca Mottola; Prabal Dutta; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Network; Energy harvesting; backscatter; RFID; Sensors; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Networked Embedded Systems (NES) are small energy-constrained devices typically with sensors, radio and some form of energy storage. The past several years have seen a rapid growth of applications of NES, with several predictions stating billions of devices deployed in the near future. LÄS MER
