  1. 1. Distributed Coded Caching with Application to Content Delivery in Wireless Networks

    Författare :Jesper Pedersen; Chalmers University of Technology; []
    Nyckelord :machine learning; erasure correcting codes; optimization; Caching; device-to-device communication; content delivery networks; time-to-live;

    Sammanfattning : The amount of content downloaded to mobile devices, mainly driven by the demand for video content, threatens to completely congest wireless networks and the trend of ever increasing video traffic is expected to continue unabated for many years. A promising solution to this problem is to store popular content closer to end users, effectively trading expensive bandwidth resources for affordable memory, a technique known as caching. LÄS MER

  2. 2. Improving the performance of distributed multi-agent based simulation

    Författare :Dawit Mengistu; Blekinge Institute of Technology; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; agent based simulation; MABS; distributed systems; application performance;

    Sammanfattning : This research investigates approaches to improve the performance of multi-agent based simulation (MABS) applications executed in distributed computing environments. MABS is a type of micro-level simulation used to study dynamic systems consisting of interacting entities, and in some cases, the number of the simulated entities can be very large. LÄS MER

  3. 3. A System, Tools and Algorithms for Adaptive HTTP-live Streaming on Peer-to-peer Overlays

    Författare :Roberto Roverso; Seif Haridi; Jim Dowling; Alberto Montresor; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer; distributed caching; nat traversal; congestion control; adaptive HTTP streaming; live streaming; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : In recent years, adaptive HTTP streaming protocols have become the de facto standard in the industry for the distribution of live and video-on-demand content over the Internet. In this thesis, we solve the problem of distributing adaptive HTTP live video streams to a large number of viewers using peer-to-peer (P2P) overlays. LÄS MER

  4. 4. Study on Decentralized Machine Learning and Applications to Wireless Caching Networks

    Författare :Yu Ye; Ming Xiao; Zhu Han; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Distributed multi-task learning; decentralized optimization; ADMM; mobility-aware wireless caching; Distribuerat lärande med flera uppgifter; decentraliserad optimering; ADMM; mobilitetsmedveten trådlös cache; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : To promote the development of distributed machine learning, it is crucial to provide efficient models and training algorithms. This thesis is devoted to the design of distributed multi-task learning and decentralized algorithms, as well as the application of distributed machine learning in wireless caching networks. LÄS MER

  5. 5. On the Performance Analysis of Large Scale, Dynamic, Distributed and Parallel Systems

    Författare :John Ardelius; Seif Haridi; Supriya Krishnamurthy; Mark Jelasity; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURAL SCIENCES; NATURVETENSKAP; Performance analysis distributed systems; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Evaluating the performance of large distributed applications is an important and non-trivial task. With the onset of Internet wide applications there is an increasing need to quantify reliability, dependability and performance of these systems, both as a guide in system design as well as a means to understand the fundamental properties of large-scale distributed systems.
