TCP is a dominant protocol for consistent communication over the internet. It provides flow, congestion and error control mechanisms while using wired reliable networks. Its congestion control mechanism is not suitable for wireless links where data corruption and its lost rate are higher. The physical links are transparent from TCP that takes packet losses due to congestion only and initiates c...

There has been an increase in the use of video surveillance and monitoring in public areas to improve safety and security. Change detection and crowding/congestion density estimation are two sub-tasks in a subway monitoring system. We propose a method that decomposes this problem into two steps. The first step consists of a change detection algorithm that distinguishes the background from the f...

Many applications require fast data transfer over high speed and long distance networks. Compound TCP(CTCP) is a novel congestion control algorithm for high-speed and long delay networks. This paper develops a discrete time dynamic feedback model of a congestion control system with CTCP under random early detection (RED). We find that periodic doubling bifurcation occurs when varying the RED co...

Road congestion is a common problem worldwide. In developed countries, automated congestion detection techniques are used in road travel assisting applications. But these techniques are mostly inapplicable in developing regions due to high cost and their assumptions of orderly traffic. We present two techniques for effective congestion detection in chaotic traffic of developing regions. Our fir...

Energy conservation and congestion control are widely researched topics in Wireless Sensor Networks in recent years. The main objective is to develop a model to find the optimized path on the basis of distance between source and destination and the residual energy of the node. This paper shows an implementation of nature inspired improved Bat Algorithm to control congestion in Wireless Sensor N...

Congestion in Wireless Sensor Network (WSN) is an issue of concern for several researchers in recent years. The key challenge is to develop an algorithmic rule which may realize the optimased route on the idea of parameters like residual energy, range of retransmissions and the distance between source and destination. The Firefly Algorithmic rule is implemented in this paper that relies on the ...

This paper studies congestion control in local wireless networks supporting transmission control protocol (TCP) under random early detection (RED). In general, congestion delays may cause instability of the routers running active queue management (AQM) protocols such as RED. Moreover, its management efficiency could be reduced by serious queue oscillation. To improve these two drawbacks, we pro...

In this paper we analyze the performance of a TCP-like ow control mechanism. The transmission rate is considered to increase linearly in time until the receipt of a congestion notiication (via loss detection in context of TCP) where the transmission rate is multiplicatively decreased. We introduce a general model based on a multi-state Markov chain for the moments at which the congestion is det...

A critical design issue of Transmission Control Protocol (TCP) is its congestion control that allows the protocol to adjust the endto-end communication rate based on the detection of packet loss. However, TCP congestion control may function poorly during its slow start and congestion avoidance phases. This is because TCP sends bursts of packets with the fast window increase and the ACK-clock ba...

The proposed system exhibit the issues of congestion in WSN which usually takes place when the quantity of the sensor motes reporting data maximizes towards sink mote. This phenomenon will cause minimization of optimal throughput and loss of valuable data. The proposed system highlights a novel approach for mitigating the ill-effects of traffic congestion in the area of wireless sensor network....
