  1. 1. Opportunistic Networking : Congestion, Transfer Ordering and Resilience

    Författare :Fredrik Bjurefors; Per Gunningberg; Christian Rohner; Mario Gerla; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Opportunistic Networking; Congestion; Transfer Ordering; Resilience; Testbed; WISENET; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Opportunistic networks are constructed by devices carried by people and vehicles. The devices use short range radio to communicate. Since the network is mobile and often sparse in terms of node contacts, nodes store messages in their buffers, carrying them, and forwarding them upon node encounters. LÄS MER

  3. 2. Opportunistic Networking : Mobility Modeling and Content Distribution

    Författare :Ljubica Pajevic; Gunnar Karlsson; Karin Anna Hummel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic networks; ad hoc networks; mobility modeling;

    Sammanfattning : We have witnessed two main trends in recent years that have shaped the current state of communication networks. First, the Internet was designed with the initial idea to provide remote access to resources in the network; today it is overwhelmingly being used for content distribution. LÄS MER

  4. 3. Challenged Networking : An Experimental Study of new Protocols and Architectures

    Författare :Erik Nordström; Per Gunningberg; Brian Levine; Uppsala universitet; []
    Nyckelord :Challenged networking; Network Architecture; Wireless Ad hoc Networks; Delay Tolerant Networks; Opportunistic Networks; Testbeds.;

    Sammanfattning : With the growth of Internet, the underlying protocols are increasingly challenged by new technologies and applications. The original Internet protocols were, however, not designed for wireless communication, mobility, long disconnection times, and varying bandwidths. LÄS MER

  5. 4. Opportunistic Content Distribution

    Författare :Ólafur Helgason; Gunnar Karlsson; Mostafa Ammar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : In recent decades, communication networks have had a profound effect on society. Wireless communication has affected our lifestyle and altered how humans communicate and the Internet has revolutionized how we access, publish and disseminate information. LÄS MER

  7. 5. Opportunistic Content Distribution : A System Design Approach

    Författare :Sylvia Todorova Kouyoumdjieva; Gunnar Karlsson; Martin May; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The penetration of smart pocket-size devices that provide constant Internet connectivity, such as mobile phones, has significantly changed the way people obtain, view and share information. Content provision is not anymore a prerogative to professionals; individuals are not solely customers, but also act as content generators and distributors. LÄS MER
