  1. 11. Reconfigurable Analog to Digital Converters for Low Power Wireless Applications

    Författare :E. Martin I. Gustafsson; Ana Rusu; Georges Gielen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated Circuits; Analog to Digital Converters; Wireless communication; Electronics Engineering; Electrical Engineering; Electronics; Elektronik;

    Sammanfattning : The commercialization of Marconi’s radio transmission and reception, along with the development of integrated circuits in the 1960’s have facilitated many new consumer products for wireless communication, where the mobile phones or handsets are one. These handsets started out as a portable phone, mounted in cars, and have with time added additional services as Short Message Service, and have today become a media center with global positioning, and high-speed internet connection.

  2. 12. 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. 13. Enabling autonomous envionmental measurement systems with low-power wireless sensor networks

    Författare :Sebastian Bader; Bengt Oelmann; Mittuniversitetet; []

  4. 14. Using Existing Infrastructure as Support for Wireless Sensor Networks

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

    Sammanfattning : 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. LÄS MER

  5. 15. Low Power Decoding Circuits for Ultra Portable Devices

    Författare :Reza Meraji; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A wide spread of existing and emerging battery driven wireless devices do not necessarily demand high data rates. Rather, ultra low power, portability and low cost are the most desired characteristics. Examples of such applications are wireless sensor networks (WSN), body area networks (BAN), and a variety of medical implants and health-care aids. LÄS MER
