  2. 1. Design and Implementation of Centrally-Coordinated Peer-to-Peer Live-streaming

    Author : Roberto Roverso; Seif Haridi; Sameh El-Ansary; Jim Dowling; Peter Van Roy; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; peer-to-peer; live-streaming; nat traversal; Electrical engineering; Elektroteknik; Computer engineering; Datorteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : In this thesis, we explore the use of a centrally-coordinated peer-to-peer overlay as a possible solution to the live streaming problem. Our contribution lies in showing that such approach is indeed feasible given that a number of key challenges are met. READ MORE

  4. 2. Towards a framework for analyzing IT strategy management in public sector : a case for IT organisations in the public sector

    Author : Anayanci López Poveda; Paul Johannesson; Lazar Rusu; Anne Håkansson; KTH; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; IT strategy management; strategic management of IT; IT service management; public sector; small medium sized IT organizations.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Small/medium sized public sector IT organisations combine several characteristics that difficult the effective use of an IT strategy. Research has reported small/medium sized organisations as using unstructured and informal IT management initiatives, which frequently leads to inexistent or incipient use of IT strategy. READ MORE

  5. 3. Enabling Internet-Scale Publish/Subscribe In Overlay Networks

    Author : Fatemeh Rahimian; Seif Haridi; Šarunas Girdzijauskas; Márk Jelasity; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Publish Subscribe; Content Distribution; Peer-To-Peer Overlay Network; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : As the amount of data in todays Internet is growing larger, users are exposedto too much information, which becomes increasingly more difficult tocomprehend. Publish/subscribe systems leverage this problem by providingloosely-coupled communications between producers and consumers of data ina network. Data consumers, i.e. READ MORE

  6. 4. Coping with Misbehavior in Mobile Ad-hoc Networks

    Author : Sonja Buchegger; Jean-Yves Le Boudec; EPFL; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; mobile ad-hoc networks; incentives; cooperation; reputation systems; Bayes; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : n this work, we address the question of how to enable a system to operate despite the presence of misbehavior. Specifically, in a mobile ad-hoc network, how can we keep the network functional for normal nodes when other nodes do not route and forward correctly? Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. READ MORE

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

    Author : John Ardelius; Seif Haridi; Supriya Krishnamurthy; Mark Jelasity; KTH; []
    Keywords : 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;

    Abstract : 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.
