  1. 16. An Efficient Access Control Method for Resource Constrained Embedded Systems

    Författare :Pablo Punal; Panos Papadimitratos; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : The way to communicate and distribute the information in Wireless Sensor Networks (WSN) is constantly under evolution; at beginning the networks sent the information using proprietary protocols; but today, using IP protocol has become widely used to improve the interoperability and to standardize. These nodes often are constrained re- source devices and are not able to use the same mechanisms that a normal computer uses, because the processing performance and memory capacity are smaller than a nor- mal computer.

  3. 17. Introducing Power Control and Link Adaptation in Flooding-based Underwater Networks : Extending the applicability of flooding-based routing protocols

    Författare :Elias Erstorp; Jacob Kuttenkeuler; Roald Otnes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic Underwater Networks; Distributed Power Control; Link Adaptation; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Underwater communication and networking are key enabling technologies for many current and future marine applications. Generally, the envisioned applications include environmental monitoring, aquaculture, and surveillance. LÄS MER

  4. 18. Programming Memory-Constrained Networked Embedded Systems

    Författare :Adam Dunkels; Mats Björkman; Thiemo Voigt; Kay Römer; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor networks; embedded systems; operating systems; programming; networking; TCP IP; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Ten years after the Internet revolution are we standing on the brink of another revolution: networked embedded systems that connect the physical world with the computers, enabling new applications ranging from environmental monitoring and wildlife tracking to improvements in health care and medicine. 98% of all microprocessors sold today are used in embedded systems.

  5. 19. Network capacity sharing with QoS as a financial derivative pricing problem : algorithms and network

    Författare :Lars Rasmusson; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A design of an automatic network capacity markets, often referred to as a bandwidth market, is presented. Three topics are investigated. First, a network model is proposed. The proposed model is based upon a trisection of the participant roles into network users, network owners, and market middlemen. LÄS MER

  7. 20. Transport-Layer Performance for Applications and Technologies of the Future Internet

    Författare :Per Hurtig; Anna Brunström; Saverio Mascolo; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TCP; SCTP; transport protocols; loss recovery; packet reordering; congestion control; performance evaluation; Computer Science; Datavetenskap;

    Sammanfattning : To provide Internet applications with good performance, the transport protocol TCP is designed to optimize the throughput of data transfers. Today, however, more and more applications rely on low latency rather than throughput. Such applications can be referred to as data-limited and are not appropriately supported by TCP. LÄS MER
