    A QoS Aware Vertical Handover in Mobile Network

    The convergence of heterogeneous wireless access technologies characterizes the 4G wireless networks. In such converged systems, the seamless and efficient handoff between different access technologies (vertical handoff) is essential and remains a challenging problem. The heterogeneous co-existence of access technologies with largely different characteristics creates a decision problem of determining...

    Live Streaming Using Peer Division Multiplexing

    A Number of commercial Peer-To-Peer (P2P) systems for live streaming have been introduced in recent years. The behavior of the popular systems has been extensively studied in several measurement papers. However, these studies have to rely on a "Black-box" approach, where packet traces are collected from a single or a...
