  2. 1. Centralized Routing for Prolonged Network Lifetime in Wireless Sensor Networks

    Author : Ewa Hansen; Mats Björkman; Mikael Nolin; Dag Nyström; Thiemo Voigt; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor networks; routing; energy efficiency; asymmetric communicaiton; communication; power consumption; computer networks; trådlösa sensornät; trådlös; kommunikation; energikonsumtion; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Abstract : In this thesis centralized routing methods for wireless sensor networks have been studied. The aim has been to prolong network lifetime by reducing the energy consumed by sensor-node communication.Wireless sensor networks are rapidly becoming common in application areas where information from many sensors is to be collected and acted upon.

  4. 2. 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

  5. 3. Long-Term Stable Communication in Centrally Scheduled Low-Power Wireless Networks

    Author : Oliver Harms; Christian-Albrechts-Universität zu Kiel; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronous Transmissions; IEEE 802.15.4; WSN; Opportunistic Routing; Time-Slotted Channel Hopping TSCH ; Industrial Internet of Things; Routing; Central Scheduling; Wireless Sensor-Actuator Networks; IoT;

    Abstract : With the emergence of the Internet of Things (IoT), more devices are connected than ever before. Most of these communicate wirelessly, forming Wireless Sensor Networks. In recent years, there has been a shift from personal networks, like Smart Home, to industrial networks. READ MORE

  6. 4. Wireless Sensor Networks for Development : Potentials and Open Issues

    Author : Marco Zennaro; Björn Pehrson; Andreas Kassler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : Wireless Sensor Networks (WSNs) provide a way to bridge the gap between the physical and the virtual worlds. They promise unprecedented abilities to observe and understand large-scale, real-world phenomena at a fine spatial-temporal resolution. READ MORE

  7. 5. Wireless video sensor network and its applications in digital zoo

    Author : Johannes Karlsson; Haibo Li; Jerry Eriksson; Oliver Wu Dapeng; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Networks; Wireless ad-hoc Networks; Digital Zoo; Video Compression; Real-Time Video Communication; Object Tracking; Sensor Fusion; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik; signalbehandling; Signal Processing;

    Abstract : Most computing and communicating devices have been personal computers that were connected to Internet through a fixed network connection. It is believed that future communication devices will not be of this type. Instead the intelligence and communication capability will move into various objects that surround us. READ MORE
