  2. 1. Compensating for Unreliable Communication Links in Networked Control Systems

    Author : Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

    Abstract : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. READ MORE

  4. 2. Interoperability Infrastructure and Incremental learning for unreliable heterogeneous communicating Systems

    Author : Abdul Haseeb; Mihhail Matskin; Jüri Vain; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interoperability; Incremental learning; Unreliable heterogeneous communicating Systems; Robotics; Computer science; Datavetenskap;

    Abstract : In a broader sense the main research objective of this thesis (and ongoing research work) is distributed knowledge management for mobile dynamic systems. But the primary focus and presented work focuses on communication/interoperability of heterogeneous entities in an infrastructure less paradigm, a distributed resource manipulation infrastructure and distributed learning in the absence of global knowledge.

  5. 3. Speech and Video Coding for Unreliable Channels

    Author : Daniel Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; joint source-channel coding; channel-optimized quantization;

    Abstract : Speech and video communications via the Internet and cellular phones have become a part of modern life. This thesis deals with different methods for speech and video transmission over noisy and lossy communication channels. READ MORE

  6. 4. Streaming Video over Unreliable and Bandwidth Limited Networks

    Author : Hussein Aziz; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Streaming video; Mobile device; Frame splitting; Sub-frame crossing; Time Interleaving Robust Streaming; Region of Interest; Mean Opinion Score;

    Abstract : The main objective of this thesis is to provide a smooth video playout on the mobile device over wireless networks. The parameters that specify the wireless channel include: bandwidth variation, frame losses, and outage time. READ MORE

  7. 5. Enhancing the Smoothness of Streaming Video for Mobile Users over Unreliable Networks

    Author : Hussein Muzahim Aziz; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Real time video streaming over wireless network is an increasingly important and attractive service to the mobile users. Video streaming involves a large amount of data to be transmitted in real time, while wireless channel conditions may vary from time to time. READ MORE
