  1. 6. System Design for Opportunistic Networks

    Författare :Sylvia T. Kouyoumdjieva; Gunnar Karlsson; Andrea Passarella; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic communication; system design; mobility; energy-saving mechanisms; device-to-device communication; mobile data offloading; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Device-to-device communication has been suggested as a complement to traditional cellular networks as a means of offloading cellular traffic. In this thesis we explore a solution for device-to-device communication based on opportunistic content distribution in a content-centric network. LÄS MER

  3. 7. Towards content distribution in opportunistic networks

    Författare :Thabotharan Kathiravelu; Arnold Pears; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Opportunistic networking is a new communication paradigm. Content Distribution in opportunistic networks is challenging due to intermittent connectivity, short connection durations and a highly dynamic topology. Research is needed to develop new applications and protocols that can distribute content in opportunistic networks. LÄS MER

  4. 8. Long-Term Stable Communication in Centrally Scheduled Low-Power Wireless Networks

    Författare :Laura Harms; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Time-Synchronization; Routing; Opportunistic Routing; Industrial Internet of Things; Bluetooth Low Energy; Internet of Things; IEEE 802.15.4; TinyML; IIoT; TSCH; Centralized Scheduling; BLE; Time-Slotted Channel Hopping; IoT; Synchronous Transmissions;

    Sammanfattning : With the growing number of Internet of Things (IoT) devices and the emergence of the Industrial Internet of Things (IIoT), there is a growing demand for adaptive and resource-efficient wireless communication protocols and systems. Industrial networks play a crucial role in monitoring pipelines and facilitating communication among collaborating devices, such as robots in a smart factory. LÄS MER

  7. 10. 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
