  1. 1. Improving Low-Power Wireless Protocols with Timing-Accurate Simulation

    Författare :Fredrik Österlind; Thiemo Voigt; Adam Dunkels; Per Gunningberg; Tarek F. Abdelzaher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Low-Power Wireless Protocols; Wireless Sensor Networks; Contiki; Cooja; Simulation; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Low-power wireless technology enables numerous applications in areas from environmental monitoring and smart cities, to healthcare and recycling. But resource-constraints and the distributed nature of applications make low-power wireless networks difficult to develop and understand, resulting in increased development time, poor performance, software bugs, or even network failures.

  3. 2. 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. 3. Scalable and Interoperable Low-Power Internet of Things Networks

    Författare :Joakim Eriksson; Thiemo Voigt; Per Gunningberg; Leo Selavo; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IoT; low-power networking; scalability; interoperability;

    Sammanfattning : Internet of Things (IoT) is the concept of connecting devices to the Internet. IoT devices can be anything from small temperature sensors to self-driving cars. The devices are typically resource-constrained, connected wirelessly, and often battery-powered. LÄS MER

  5. 4. Programming Memory-Constrained Networked Embedded Systems

    Författare :Adam Dunkels; Mats Björkman; Thiemo Voigt; Kay Römer; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor networks; embedded systems; operating systems; programming; networking; TCP IP; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Ten years after the Internet revolution are we standing on the brink of another revolution: networked embedded systems that connect the physical world with the computers, enabling new applications ranging from environmental monitoring and wildlife tracking to improvements in health care and medicine. 98% of all microprocessors sold today are used in embedded systems.
