    Abstract : In recent years, Internet and IP technologies have made inroads into almost every communication market ranging from best-effort services such as email and Web, to soft real-time applications such as VoIP, IPTV, and video. However, providing a transport service over IP that meets the timeliness and availability requirements of soft real-time applications has turned out to be a complex task. READ MORE

  7. 5. Creating always-best-connected multimedia applications for the 4:th generation wireless systems

    Author : Johan Kristiansson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Abstract : This thesis describes an application-layer framework for managing network connectivity in the 4th-generation wireless systems, which will consist of overlapping heterogeneous networks. If multiple access networks are present, users will have a choice to access the Internet through the “best” available network. READ MORE
