In this paper we address the issue of robust and efficient scalable video communication by integrating an end-end buffer management and congestion control at the source with the frame rate playout adjustment mechanism at the receiver. The proposed scheme is based on the observation that when congestion control is implemented at the source, most of the loss occurs at the source and not within th...

OBJECTIVE To determine portal hemodynamic changes associated with surgical shunt ligation and establish ultrasonographic criteria for determining the optimal degree of shunt narrowing and predicting outcome. DESIGN Case series. ANIMALS 17 dogs, each with a single congenital extrahepatic portosystemic shunt. PROCEDURE Pre- and postligation flow velocities and flow directions were determine...

Civil buildings are prone to various kinds of damages. The detection of damages caused in a building at an early stage is essential in order to save the invaluable human life and significant belongings. Wireless sensor networks (WSN) help to detect damages caused to a building by sensing different factors, which affect civil structures. Energy efficiency of sensor nodes and network congestion a...

The performance of transport layer protocols can be affected differently due to wireless congestion, as opposed to network congestion. Using an active network evaluation strategy in a real world test-bed experiment, the Transport Control Protocol (TCP), Datagram Congestion Control Protocol (DCCP), and Stream Control Transport Protocol (SCTP) were evaluated to determine their effectiveness in te...

Here in this paper A MAC layer level congestion detection mechanism has been proposed. The proposed model aims to deliver an energy efficient mechanism to quantify the degree of congestion at victim node with maximal accuracy. This congestion detection mechanism is integrated with a Two-Step Cross Layer Congestion Control Routing Protocol. The proposed model involves controlling of congestion i...

One hypothesized contributor to vision changes experienced by >75% of International Space Station astronauts is elevated intracranial pressure (ICP). While no definitive data yet exist, elevated ICP might be secondary to the microgravity-induced cephalad fluid shift, resulting in venous congestion (overfilling and distension) and inhibition of cerebrospinal and lymphatic fluid drainage from the...

Increased reliability is necessary if the Internet is to carry information such as voice, video and other enhanced services. Congestion in the network because of the statistical nature of packet forwarding is a serious issue that could impede achieving the reliable, timely delivery of data and quality of service. At present humans monitor the network for congestion with a variety of data collec...

The IETF’s standard congestion control schemes have been widely shown to be inadequate for various environments (e.g., high-speed networks). Recent research has yielded many alternate congestion control schemes that significantly differ from the IETF’s congestion control principles. Using these new congestion control schemes in the global Internet has possible ramifications to both the traffic ...

A discussion of the causes and impacts of recurring and non-recurring congestion accompanied with a review of potential solutions and existing examples. While congestion is a broad and subjective matter, research focused on the separate causes of recurring congestion – mainly capacity and behavioral issues – and non-recurring congestion – mainly incidents which cause unexpected congestion and t...

The Internet includes various ranges of applications such as multimedia, voice and data but it endures rigorous network congestion. Further, congestion detection is an essential preventive measure must be taken to provide congestion-free Internet. To stipulate proficient technique for congestion detection, in this paper, we propose a load aware congestion detection technique in the Internet. To...
