  1. 11. Internet of things for monitoring grazing animals

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Alisher Zaitov; [2016]
    Nyckelord :;

    Sammanfattning : Swedish agricultural industry is well known for it’s fair animal tending and ecological processes, the high standards comes at a cost of tough strict regulations. Laws were introduced to keep a low level usage of antibiotics and toxic products among the agricultural industry. LÄS MER

  3. 12. Battery Lifetime Modelling and Validation of Wireless Building Automation Devices in Thread

    Master-uppsats, KTH/Kommunikationsnät

    Författare :Eva Azoidou; [2016]
    Nyckelord :Internet of Things IoT ; battery lifetime; wireless sensor networks; energy efficiency; IEEE 802.15.4 MAC; power consumption model; Thread;

    Sammanfattning : The need for energy efficiency in wireless communication is prevalent in all areas, but to an even greater extent in low-power and lossy networks that rely on resource-constrained devices. This degree project seeks to address the problem of modelling the battery lifetime of a duty-cycled node, participating in a wireless sensor network that is typically used in smart home and building applications.

  4. 13. Hosting a building management system on a smart network camera: On the development of an IoT system

    Kandidat-uppsats, Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Författare :Alf Stenbrunn; Theodor Lindquist; [2015]
    Nyckelord :Internet of Things; IoT; Sensors; Multiple Sensor Device; MSD; Network camera; Building management; Distributed systems; Sensor; Building Management System; Byggnadsstyrsystem; Nätverkskamera; Sensor network; Wireless Sensor Network; WSN; Sensornätverk; Trådlöst sensornätverk; Distribuerade system; Sakernas internet; Fastighetsautomation;

    Sammanfattning : The Internet of Things (IoT) is an umbrella term for smart things connected to the Internet. Connected sensors may be used to the benefit of smart building management systems. This thesis describes the development of a sensor based building management system prototype, lightweight enough to run on a single network camera. LÄS MER

  5. 14. A Self-organized Wireless Sensor Network (WSN) for a Home-event Managed System : Design of a cost efficient 6LoWPAN-USB Gateway with RFID security

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Sergio Floriano Sanchez; [2015]
    Nyckelord :;

    Sammanfattning : Wireless Sensor Networks (WSN) have existed for many years in industry applications for different purposes but their use has not been fully extended to the global consumers. Sensor networks have lately resulted to be greatly helpful to people in everyday life, specially in home automation applications for monitoring events, security, and control of devices and different elements in the house by using actuators.

  7. 15. Synchronous sleep in a wireless mesh network : Using synchronous sleep schedule, in a wireless sensor network for indoor climate control, to save power enabling battery powered network

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Fredrik Isaksson; [2014]
    Nyckelord :;

    Sammanfattning : För att styra inomhusklimat behövs det ett styrsystem med återkoppling. Det finns flera olika sätt att återkoppla, men en av möjligheterna är att använda ett trådlöst nätverk med sensorer. I trådlösa sensornätverk vill man alltid spara energi för att få längre batteritid. Det finns flera olika tekniker för att uppnå det. LÄS MER
