  5. 4. Scalability of Device-to-Device Communications in Cellular Networks

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Daniel Verenzuela; [2014]
    Nyckelord :;

    Sammanfattning : In current cellular networks the demand of traffic is rapidly increasing and new techniques need to be developed to accommodate future service requirements. Device-to-Device (D2D) communications is one technique that has been proposed to improve the performance of the system by allowing devices to communicate directly without routing traffic through the base station.
