  1. 16. Multichannel Communication in Contiki's Low-power IPv6 Stack

    Master-uppsats, Institutionen för informationsteknologi

    Författare :Beshr Al Nahas; [2013]
    Nyckelord :;

    Sammanfattning : Vast majority of wireless appliances used in household, industry and medical field share the ISM frequency band. These devices need to coexist and thus are challenged to tolerate their mutual interference. One way of dealing with this is by using frequency hopping; where the device changes its radio channel periodically. LÄS MER

  3. 17. Wireless Solutions and Authentication Mechanisms for Contiki Based Internet of Things Networks

    Magister-uppsats, Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Samet KALYONCU; [2013]
    Nyckelord :Internet of things;

    Sammanfattning : Internet of Things, is a new expression described as the future of the internet, promises a new world surrounded by tiny smart objects interacting with the environment, communicating with each other, and controlled over internet. Investigating which low power wireless solution and authentication mechanism fits best for IoT networks, and applying these technologies on simulator and real hardware is the main task of this project.

  7. 20. Scalable Data Collection for Mobile Wireless Sensor Networks

    Master-uppsats, KTH/Kommunikationsnät

    Författare :Navid Hassanzadeh; [2012]
    Nyckelord :;

    Sammanfattning : In the near future WSNs (wireless sensor networks) which consist of tiny wireless embedded systems will be an inseparable part of our daily lives. Data collection, collecting data from a large number of sources to one or more base stations, is a typical application for WSNs. LÄS MER
