  1. 41. Optimal Networking in Wirelessly Powered Sensor Networks

    Författare :Rong Du; Carlo Fischione; Ming Xiao; Aylin Yener; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 42. Some Aspects of Mobile Map Services

    Författare :Hanna Stigmar; Fastighetsvetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amount of information; information services; cartography; map; mobile map services; usability;

    Sammanfattning : The technology of today, with the use of computers and the Internet, has enabled new types of map usage. Screen maps provide possibilities that could never be offered by standard paper maps, and allow maps to be integrated into information services. LÄS MER

  4. 43. 5G Backhauling with Software-defined Wireless Mesh Networks

    Författare :Ricardo Santos; Andreas Kassler; Rui L. Agar; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SDN; wireless backhaul; heterogeneous networks; mmWave; 5G; resiliency; Computer Science; Datavetenskap;

    Sammanfattning : Current technological advances have caused an exponential growth of the number of mobile Internet-connected devices, along with their respective traffic demands. To cope with this increase of traffic demands, fifth generation (5G) network architectures will need to provide multi-gigabit capacity at the access base stations (BSs), through the deployment of ultra-dense small cells (SCs) operating with millimeter-wave (mmWave) frequencies, e.

  5. 44. Cooperative Context-Aware Setup and Performance of Surveillance Missions Using Static and Mobile Wireless Sensor Networks

    Författare :Edison Pignaton de Freitas; Tony Larsson; Carlos Eduardo Pereira; Franz Josef Rammig; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surveillance systems; Wireless sensor network; Cooperative sensors; Mobile sensors; Biologically-inspired networking; Context awareness;

    Sammanfattning : Surveillance systems are usually employed to monitor wide areas in which their usersaim to detect and/or observe events or phenomena of their interest. The use ofwireless sensor networks in such systems is of particular interest as these networks can provide a relative low cost and robust solution to cover large areas. LÄS MER

  7. 45. TCP in Wireless Networks: Challenges, Optimizations and Evaluations

    Författare :Stefan Alfredsson; Anna Brunström; Lars-Åke Larzon; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless networks; TCP IP; TCP-L; Network emulation; Computer science; Datavetenskap; Computer Science; Datavetenskap;

    Sammanfattning : This thesis presents research on transport layer behavior in wireless networks. As the Internet is expanding its reach to include mobile devices, it has become apparent that some of the original design assumptions for the dominant transport protocol, TCP, are approaching their limits.
