  1. 1. Contributions to IP-based wireless communications

    Författare :Héctor Luis Velayos Munoz; KTH; []
    Nyckelord :;

    Sammanfattning : The introduction of IP-based communications in wirelesssystems posed several research issues. In this thesis, wepresent different contributions to address some of the issuesin terminals and radio access networks. Firstly, we look atapplication adaptation to varying levels in quality of service(QoS). LÄS MER

    Sammanfattning : With the advent of wireless sensor networks (WSN) and success of wirelesscommunication in the local and personal area networks such asWi-Fi and Bluetoothmore serious efforts to apply standard wireless communication in sensitiveindustrial networks were initiated. This effort resulted in the standardizationof WirelessHART. LÄS MER

  7. 5. Three problems with internetworking in cellular networks

    Författare :Lars-Åke Larzon; []
    Nyckelord :;

    Sammanfattning : Over the last decade, cell phones have gone from providing the traditional interactive voice service to also include support for Internet services. Cellular networks that originally were designed for cost-efficient voice services supply low bandwidth, high error rates and long round-trip delays, which poorly fit the generous header sizes, lack of error tolerance and reliance on retransmissions of the Internet.
