In the recent times many accessible congestion control procedures have no capability to differentiate involving two major problems like packet loss by link crash and packet loss by congestion. Consequently these resolutions effect in form of wastage of possessions because they target only on the packet drop by link crash that has a needless importance. Consumption of energy and possessions in o...

This paper proposes an agent model with adaptive weight-based multi-objective algorithm to manage road-network congestion problem. Our focus is to construct a quantitative index series to describe the road-network congestion distribution, and use such indexes as weights in the multi-objective algorithm to shunt vehicles on those congested links. First, a multi-agent system is built, where each ...

We believe that the emergence of congestion control mechanisms for relatively-smooth congestion control for unicast and multicast traffic can play a key role in preventing the degradation of end-to-end congestion control in the public Internet, by providing a viable alternative for multimedia flows that would otherwise be tempted to avoid end-to-end congestion control altogether. The design of ...

Congestion is a main challenge in modern network environment. Unawareness of the network topology the network devices are demand to provide sufficient and structured connection establishment to the network. Nowadays Mobile Adhoc Network (MANET) plays a vital role in the modern networks. Because MANET can constructs its network a nd its paths based upon the current circumstances. Due to this ins...

In determining the marginal cost of congestion, economists have traditionally relied upon directly measuring traffic congestion on network links, disregarding any “network effects,” since the latter are difficult to estimate. While for simple networks the comparison can be done within a theoretical framework, it is important to know whether such network effects in real large-scale networks are ...

A Wireless Sensor Network (WSN) is a set of sensor nodes, whereby the nodes are equipped with multimedia devices such as cameras and microphones. Thus a WSN will have the capability to transmit multimedia data, such as still pictures, stream video, voice and monitoring data. In WSN during video transmission there is a chance of congestion occurrence. Congestion may cause multiple packet losses,...

End-to-end congestion control mechanisms help utilize network resources more optimally because they inherently cooperate with the congestion control mechanisms inside the network. Recent research has shown that coordinating congestion control strategies between flows can improve the performance of the group of flows as a whole. An important aspect of such congestion management is identifying fl...

TCP congestion control works well in wired Internet network but it is difficult to determine a good congestion window in a heterogeneous wireless network that consists of the wired Internet and various types of wireless networks. Therefore, we propose herein a novel adaptive window congestion control, namely TCP-Taichung, for TCP connections in heterogeneous wireless networks. The proposed RTT-...

In this paper, a congestion aware multipath routing protocol in mobile ad hoc networks (MANET) is proposed. The paths which have better bandwidth will be initially selected. For selected paths, first the congestion status of the node is found by using the early congestion detection technique which is based on the queue status and data arrival rate of the nodes. The delay includes weighted chann...

Linear Increase/Multiplicative Decrease (LIMD) has typically been the congestion control paradigm of choice in the Internet. However, a major drawback of LIMD is that it reacts identically (and aggressively) to all packet losses, irrespective of the cause of loss. In this paper, we try to augment the basic LIMD congestion control with additional mechanisms to predict the cause of packet losses ...
