This paper studies the stability and stabilization problems for networked control systems with partially known transition probabilities by using time-varying sampling period method with both packet losses and time-varying time delay where the main focus is the packet-loss issue, packet-loss process is the Markovian packet-loss process and the transition probabilities do not need completely know...

We investigate the effect of network errors on Embedded Zerotree Wavelet (EZW) encoded images and propose modifications to the EZW coder to increase error resilience in bursty packet loss conditions. A hybridencoding scheme that uses data interleaving to spread correlated information into independently processed groups and layered encoding to protect significant information within each group is...

Anecdotal evidence suggests that the quality of many videoconferences in the Internet is mediocre because of high packet loss rates. This makes it important to dee sign and implement mechanisms that minimize packet loss and its impact in video (and audio) applications. There are two such types of mechanisms. Rate control mechanisms attempt to minimize the amount of packet loss by matching the b...

MANEMO is the integration of Network Mobility (NEMO) and Mobile Ad Hoc Network (MANET). A MANEMO node has an interface to both a MANET and NEMO network, and therefore should choose the optimal interface for packet delivery, however such a handover between interfaces will introduce packet loss. We define the steps necessary for a MANEMO handover, using Mobile IP and NEMO to signal the new bindin...

Endpoint admission control solutions, based on probing a transmission path, have been proposed to meet quality requirements of audio–visual applications with little support from routers. In this paper we present a mathematical analysis of a probe–based admission control solution, where flows are accepted or rejected based on the packet–loss statistics in the probe stream. The analysis relates s...

Handover is one of the most important factors that may degrade the performance of TCP connections and real-time applications in wireless data networks. We developed a loss-free handover scheme called LPM (Last Packet Marking) for IEEE 802.16e-based broadband wireless access networks. By integrating MAC and network layer handovers efficiently, LPM minimizes the handover delay and eliminates pack...

In this paper, we analyze the jitter and packet loss behavior of voice over Internet protocol (VoIP) traffic by means of networks measurements and simulations results. As result of these analyses, we provide a detailed characterization and accurate modeling of these Quality of Service (QoS) parameters. Our studies have revealed that VoIP jitter can be modeled by selfsimilar and multifractal mod...
