We introduce a receiver-oriented approach to congestion control, demonstrated by an experimental protocol, TCP-Real. The protocol allows for a measurement-based transmission strategy, which complements the "blind" increase/decrease window adjustments. Owing to its design, the protocol displays an inherent property to produce comprehensive dynamics in heterogeneous environments with wired or wir...

Random Early Detection (RED) has been introduced as a congestion avoidance algorithm for the Internet. RED detects congestion by estimating the average queue size. It drops packets probabilistically before buuer overrow, with the drop probability depending on the average queue size. In this paper, we analyse the innuence of RED on the packet loss ratio and the throughput of a system consisting ...

In this paper, we introduce a router-based system to defend against Distributed Denial of Service (DDoS) attacks. DDoS attacks are treated as a congestioncontrol problem. The main issue is to identify the congestion and then pushback a packet filter to the router closest to the source that causes congestion. Unlike previous approaches, we propose an anomaly detection scheme using source informa...

Network trafficking is the major research area nowadays since huge amount of data is being used in various forms. A major problem which is widely considered in network trafficking is congestion and apart from the congestion another problem is that the data is accessed without proper authorization. This paper describes the congestion control algorithm, RED which improves the latency by controlli...

A congestion avoidance scheme allows a network to operate in the region of low delay and high throughput. Such scheme prevent a network from entering in to congested state. RED(Random Early Detection), is one such congestion avoidance mechanism used for effectively control of congestion. In RED, router uses only the average queue size, as a congestion indicator and the average queue length is i...

Performance of existing TCP implementations over Optical Burst Switched (OBS) networks is not satisfactory, as they suffer from false congestion detection. As the contention induced losses are more common than congestion induced losses in OBS, the TCP reduces the congestion window even when there is no congestion. This effect, in turn unnecessarily reduces the TCP throughput. So it is crucial t...

Due to dense deployment and innumerable amount of traffic flow in wireless sensor networks (WSNs), congestion becomes more common phenomenon from simple periodic traffic to unpredictable bursts of messages triggered by external events. Even for simple network topology and periodic traffic, congestion is a likely event due to time varying wireless channel condition and contention caused due to i...

Since random early detection (RED) was proposed in 1993, many active queue management (AQM) algorithms have been proposed to support better end-to-end Transmission Control Protocol (TCP) congestion control. In this article, the authors introduce and analyze a feedback control model of the TCP/AQM dynamics. Then they suggest the concept of an AQM algorithm that can detect and avoid congestion pr...

Mobile ad hoc network is a network without infrastructure where every node has its own protocols and services for powerful cooperation in the network. Every node also has the ability to handle the congestion in its queues during traffic overflow. Traditionally, this was done through DropTail policy where the node drops the incoming packets to its queues during overflow condition. Many studies s...

This article examines the economics of traveler information from probe vehicles to understand how many probes are needed to provide useful information and how that probe information might be supplied to travelers. Probes differ from permanently installed roadway detection devices both because they provide information that is less current and because an information system centered on this techno...
