  3. 2. 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

  4. 3. Window-based congestion control : Modeling, analysis and design

    Författare :Niels Möller; Karl Henrik Johansson; Rayadurgam Srikant; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet; Congestion control; Window-based; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis presents a model for the ACK-clock inner loop, common to virtually all Internet congestion control protocols, and analyzes the stability properties of this inner loop, as well as the stability and fairness properties of several window update mechanisms built on top of the ACK-clock. Aided by the model for the inner-loop, two new congestion control mechanisms are constructed, for wired and wireless networks. LÄS MER

    Sammanfattning : One of the major challenges cities face today, in their development towards sustainable urban areas, is the need for an efficient and environmentally friendly transport system. This transport system should manage to tie together the city without strong adverse impact on urban environment, air-quality and climate change. LÄS MER
