  1. 1. Wireless Multi Hop Access Networks and Protocols

    Detta är en avhandling från Faculty of Engineering, LTH at Lund University

    Författare :Anders Nilsson Plymoth; Lunds universitet.; Lund University.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi Hop Access; Wireless Networks; Mobile IP; Performance Evaluation; Medium Access Control; Routing; Wireless Ad hoc Networks;

    Sammanfattning : As more and more applications and services in our society now depend on the Internet, it is important that dynamically deployed wireless multi hop networks are able to gain access to the Internet and other infrastructure networks and services. This thesis proposes and evaluates solutions for providing multi hop Internet Access. LÄS MER

  2. 2. State-based Channel Access for a Network of Control Systems

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Chithrupa Ramesh; KTH.; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; multiple access; event-based; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Wireless networked control systems use shared wireless links to communicate between sensors and controllers, and require a channel access policy to arbitrate access to the links. Existing multiple access protocols perform this role in an agnostic manner, by remaining insular to the applications that run over the network. LÄS MER

  3. 3. Extended certificate management system : design and protocols

    Detta är en avhandling från Kista : Data- och systemvetenskap

    Författare :Nada Kapidzic Cicovic; KTH.; [1997]
    Nyckelord :;

    Sammanfattning : This thesis presents an Extended Certificate ManagementSystem (ECMS), a possible solution for a global certificationinfrastructure. The system is based on a combined trust modelthat interconnects different types of security domains, fromindividual users, small organisations to arbitrarily complexorganisations. LÄS MER

  4. 4. Human factors and wireless network applications more bits and better bits

    Detta är en avhandling från Umeå : Datavetenskap

    Författare :Greger Wikstrand; Umeå universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human factors; Mobile multimedia; Access protocols; Computer network performance; Quality of service; Video conferencing; Computer games; Streaming video; Medium access control; Collision detection; Reliable multicast; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : I avhandlingen beskrivs ett hypotetiskt system som kan användas av mobila användare, bland andra taxichaufförer, som exempelvis vill följa en viktig fotbollsmatch. Flera faktorer ställer till problem: Ibland står bilen still och föraren har inget annat att tänka på än matchen. LÄS MER

  5. 5. Contributions to Performance Modeling and Management of Data Centers

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Rerngvit Yanggratoke; KTH.; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud computing; distributed management; resource allocation; gossip protocols; management objectives; distributed object store; object allocation policy;

    Sammanfattning : Over the last decade, Internet-based services, such as electronic-mail, music-on-demand, and social-network services, have changed the ways we communicate and access information. Usually, the key functionality of such a service is in backend components, which are located in a data center, a facility for hosting computing systems and related equipment. LÄS MER
