  1. 1. Robust Low-Cost Multiple Antenna Processing for V2V Communication

    Författare :Chouaib Bencheikh Lehocine; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directional antennas; Beamforming; Multiple antennas; Periodic communication; Broadcast V2V communication; Hybrid combining;

    Sammanfattning : Cooperative V2V communication with frequent, periodic broadcast of messages between vehicles is a key enabler of applications that increase traffic safety and traffic efficiency on roads. Such broadcast V2V communication requires an antenna system with omnidirectional coverage, which is difficult to achieve using a single antenna element. LÄS MER

  3. 2. Delay-sensitive wireless communication for cooperative driving applications

    Författare :Annette Böhm; Magnus Jonsson; Elisabeth Uhlemann; Javier Gozalvéz; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative driving applications; wireless communication;

    Sammanfattning : Cooperative driving holds the potential to considerably improve the level of safety and efficiency on our roads. Recent advances in in-vehicle sensing and wireless communication technology have paved the way for the development of cooperative traffic safety applications based on the exchange of data between vehicles (or between vehicles and road side units) over a wireless link.

  4. 3. Multi-Hop Real-Time Communication over Switched Ethernet Technology

    Författare :Mohammad Ashjaei; Thomas Nolte; Moris Behnam; Jean-Luc Scharbarg; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Switched Ethernet technology has been introduced to be exploited in real-time communication systems due to its features such as its high throughput and wide availability, hence being a cost-effective solution. Many real-time switched Ethernet protocols have been developed, preserving the profits of traditional Ethernet technology, to overcome the limitations imposed by using commercially available (COTS) switches.

  5. 4. An Empirical Study of the Global Behavior of Structured Overlay Networks as Complex Systems

    Författare :Ruma R. Paul; Vladimir Vlassov; Alberto Montresor; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex Computing Systems; Designing Complex Systems; Structured Overlay Networks; Hostility of Operating Environments of Computing Systems; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Distributed applications built on top of Structured Overlay Networks (SONs) operate based on certain self-* behaviors of the underlying Peer-to-Peer network. Among those, self-organization and self-healing are the two most prominent and assumed properties. LÄS MER

  7. 5. Fibre-Optic AWG Networks Supporting Real-Time Communication in High-Performance Embedded Systems

    Författare :Kristina Kunert; Magnus Jonsson; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time communication; medium access control MAC protocol; traffic dependency analysis; network architecture; Arrayed Waveguide Grating AWG ; optical communication; real-time analysis; optical network; Computer engineering;

    Sammanfattning : High-performance embedded systems communicating heterogeneous traffic with high bandwidth and strict timing requirements are in need of more efficient communication solutions. This thesis proposes two multi-wavelength passive optical networks able to meet these demands. LÄS MER
