  1. 6. Optimal Networking in Wirelessly Powered Sensor Networks

    University dissertation from KTH Royal Institute of Technology

    Author : Rong Du; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless energy transfer; network lifetime; energy beamforming; IoT; smart cities; sensor networks; scheduling; optimization; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Wireless sensor networks (WSNs) are nowadays widely used for the long-term monitoring of small or large regions, such as lakes, forests, cities, and industrial areas. The performance of a WSN typically consists of two aspects: i) the monitoring performance, e.g. READ MORE

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

    University dissertation from KTH Royal Institute of Technology

    Author : Du Rong; KTH.; [2016]
    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.

  3. 8. Energy Constrained Wireless Sensor Networks Communication Principles and Sensing Aspects

    University dissertation from Uppsala : Institutionen för teknikvetenskaper

    Author : Erik Björnemo; Uppsala universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik 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. 9. Constraint Programming for Wireless Sensor Networks

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Farshid Hassani Bijarbooneh; Uppsala universitet.; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Constraint programming; wireless sensor networks; optimisation; macroprogramming; task mapping; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Abstract : In recent years, wireless sensor networks (WSNs) have grown rapidly and have had a substantial impact in many applications. A WSN is a network that consists of interconnected autonomous nodes that monitor physical and environmental conditions, such as temperature, humidity, pollution, etc. READ MORE

  5. 10. Centralized Routing for Prolonged Network Lifetime in Wireless Sensor Networks

    University dissertation from Akademin för innovation, design och teknik

    Author : Ewa Hansen; Mälardalens högskola.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor networks; routing; energy efficiency; asymmetric communicaiton; communication; power consumption; computer networks; trådlösa sensornät; trådlös; kommunikation; energikonsumtion; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik 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.
