  2. 1. Energy Constrained Wireless Sensor Networks : Communication Principles and Sensing Aspects

    Author : Erik Björnemo; Anders Ahlén; Mikael Sternad; Erik Larsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; Signal processing; Signalbehandling;

    Abstract : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. READ MORE

  4. 2. On Spectrum Sensing for Secondary Operation in Licensed Spectrum : Blind Sensing, Sensing Optimization and Traffic Modeling

    Author : Mohamed Hamid; Ben Slimane Slimane; Niclas Björsell; Octavia Dobre; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Spectrum Sensing; Sensing Optimization; Blind Sensing; Traffic Modelling; Energy detection; Maximumum-minimum Eigenvalue Detection; Discriminant anlysis; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : There has been a recent explosive growth in mobile data consumption. This, in turn, imposes many challenges for mobile services providers and regulators in many aspects. One of these primary challenges is maintaining the radio spectrum to handle the current and upcoming expansion in mobile data traffic. READ MORE

  5. 3. Consensus Trade-offs in Wireless Sensor Networks

    Author : CHRISTOPHER LINDBERG; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Algorithms; Wireless Sensor Networks; Compressed Sensing; Consensus Algorithms; Trade-off Analysis;

    Abstract : As more and more everyday electronic devices become equipped with the combined re- sources of computation, sensing, and wireless communications, possible platforms for implementation of wireless sensor networks have become ubiquitous. The combination of these three main capabilities of such a network present the opportunity to for example gather high resolution measurement data, or cooperatively perform advanced computa- tional tasks.

  6. 4. Synchronous and Concurrent Transmissions for Consensus in Low-Power Wireless

    Author : Beshr Al Nahas; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Consesnsus; IoT; IIoT; Capture Effect; Distributed Computing; Wireless Networks; Sensing; TSCH; Bluetooth; Industrial Internet of Things; WSN; Concurrent Transmissions;

    Abstract : With the emergence of the Internet of Things, autonomous vehicles and the Industry 4.0, the need for dependable yet adaptive network protocols is arising. Many of these applications build their operations on distributed consensus. For example, UAVs agree on maneuvers to execute, and industrial systems agree on set-points for actuators. READ MORE

  7. 5. Wireless Sensor Networks in Smart Cities : The Monitoring of Water Distribution Networks Case

    Author : Du Rong; Carlo Fischione; Ming Xiao; Iordanis Koutsopoulos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer Programming; Nonconvex Optimization; Network Lifetime; Dynamic; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The development of wireless sensor networks (WSNs) is making it possible to monitor our cities. Due to the small size of the sensor nodes, and their capabilities of transmitting data remotely, they can be deployed at locations that are not easy or impossible to access, such as the pipelines of water distribution networks (WDNs), which plays an important role in protecting environment and securing public health.
