  1. 16. Model-driven Alignment : Linking Business Strategy with Information Systems

    Författare :Constantinos Giannoulis; Jelena Zdravkovic; John Krogstie; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Alignment; Business; Strategy; Information; Systems; Requirements; IS; Enterprise; Models; Modeling; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Information technology (IT) is more pervasive than ever before, constituting a significant factor for performance and survival in the business arena. It is essential that IT within organizations understands what the Business needs in order to provide the necessary support and bring value, which is also true when IT is also the main value creator.

  2. 17. A Node-Link Perspective on the Impact of Local Conditions in Sensor Networks

    Författare :Hjalmar Wennerström; Lars-Åke Nordén; Christian Rohner; Lars Wolf; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; opportunistic communication; meterlological impact; packet corruption; multi-contacts; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Sensor networks are made up of small battery-powered sensing devices with wireless communication capabilities, enabling the network to monitor the environment in which it is deployed. Through their flexible and cable-free design these networks open up for new deployment scenarios that were previously not plausible such as during a natural disaster. LÄS MER

  3. 18. Cooperative Communication for Increased Reliability in Industrial Wireless Networks

    Författare :Svetlana Girs; Mats Björkman; Lucia Lo Bello; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Introducing wireless networks into distributed industrial systems may enable new or improved application areas and also great cost reductions due to lower complexity of installation and maintenance, compared to existing wired solutions. However, signals travelling through wireless channels are affected by pathloss, fading and shadowing, and, as a result, packet errors are both time-varying and more frequent than in e. LÄS MER

  4. 19. Interference alignment and power control for wireless interference networks

    Författare :Hamed Farhadi; Mikael Skoglund; Michail Matthaiou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference alignment; power control; limited feedback; wireless communication; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : This thesis deals with the design of efficient transmission schemes forwireless interference networks, when certain channel state information(CSI) is available at the terminals.In wireless interference networks multiple source-destination pairsshare the same transmission medium for the communications.

  5. 20. Dynamic Traffic Control in Multiservice Networks - Applications of Decision Models

    Författare :Ulf Ahlfors; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed-Memory Systems; Overload Control; Call Admission Control; Routing; Optimization; Multiservice Networks; Markov Decision Process; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. LÄS MER
