    Sammanfattning : Wireless Sensor Networks (WSNs) are ad-hoc wireless networks for small form-factor embedded nodes with limited memory, processing and energy resources. Certain applications, like industrial automation and real-time process monitoring requires time synchronized reliable network protocol. LÄS MER

  4. 8. Remote Surveillance and Measurement

    Kandidat-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Muhammad Rashid; Mumtaz Mutarraf; [2008]
    Nyckelord :Wireless Sensor Network; Adaptiveness; Surveillance; nesC TinyOS;

    Sammanfattning : Wireless Sensor Network (WSN), a collection of “sensor nodes” promises to change the scientist’s approach of gathering the environmental data in various fields. Sensor nodes can be used for non-stop sensing, event detection, location sensing and local control of actuators, this concept gives surety to many latest application areas like agriculture, military, home or factory automation, logistics and so on.

  5. 9. Reliable Data Delivery over Wireless Sensor Networks

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Per-Erik Björkstad; [2007]
    Nyckelord :;

    Sammanfattning : In this thesis we present ReDaR, a software and hardware environment for reliable data retrieval from multiple remotely located wireless sensor networks (WSNs). The software is programmed in Java and NesC over TinyOS, and allows for direct interaction with individual sensors using a graphical user interface running on a remote client. LÄS MER

  7. 10. Open Secure Office Project : Wireless Sensor Network

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Rikard Andersson; Martin Sandberg; László Urszuly; [2005]
    Nyckelord :Wireless sensor network; Open secure office; TinyOS; NesC;

    Sammanfattning : In recent years, the development of wireless sensor networks has made a great progress. Early projects focused on replacement of existing systems equipped with wires. These systems started out as simple static data collection networks with one smart central node that could decide further actions based on the content of the collected data. LÄS MER
