In this paper, we discuss a cross layer congestion control technique of TCP Reno-2 in wireless networks. In this both TCP layer and PHY layer jointly control congestion. The PHY layer changes transmission power as per the channel condition, interference received and congestion in the network, whereas the TCP layer controls congestion using Reno-2 window based flow control. Our simulations show ...

We consider the burst-level congestion control problem in a communication network with multiple traffic sources, modeled as infinite banks of fluid traffic. The controlled traffic shares a common bottleneck node with highpriority cross traffic modeled as Markov-modulated fluid. We introduce a simulation-based congestion control scheme capable of performing effectively under rapidly-varying serv...

The main objective of congestion control in VANET is to best exploit the available network resources and to minimize the congestion in the network. In this context, we present a congestion control approach, based on time synchronization approach reducing number of messages, to ensure reliable and safe communication within VANET. It supports discarding of similar types of messages and time synch...

As traffic patterns and network topologies become more and more complicated in current enterprise data centers and TOP500 supercomputers, the probability of network congestion increases. If no countermeasures are taken, network congestion causes long communication delays and degrades network performance. A congestion control mechanism is often provided to reduce the consequences of congestion. ...

Congestion is the problem that occurs due to saturation of network resources. Despite the implementation of traditional congestion control algorithms such as Transmission Control Protocol (TCP/IP), congestion remains a critical issue in computer and ATM networks. Fuzzy Logic is applied to solve the congestion control problem as communication networks are difficult to model using traditional con...

Current parallel applications in parallel computing systems require an interconnection network to provide low and bounded communication delays. Communication characteristics such as traffic pattern and communication load change over time and, eventually, they may exceed network capacity causing congestion and performance degradation. Congestion control based on adaptive routing should be applie...

Congestion Control performs a very important role in Computer Networks, Modern Telecommunication, Internet and both wired and wireless communications are being intended for high-speed communication of large amounts of data. Due to lack of proper Congestion control mechanism the congestion collapse of such networks would become highly complex. A network with Streamed media traffic is a challenge...

Congestion on the roads is a key problem to deal with, which wastes valuable time.. Due to high mobility rate and relative speed link failure occur very often. VANET is used to tackle the problem of congestion, and make decisions well in advance to avoid traffic congestion. In this paper we proposed a solution to detect and control the traffic congestion by using of both (V2V) and (V2I), as a r...

ALAPATI V. S. REDDY works in the Cellular Digital Packet Data Group at BNR, Richardyon. ongestion control in packet-switching networks became a high priority in network design and research due to ever-growing network bandwidth and intensive network applications. Dozens of various congestion conGol strategies have been proposed, and more are forthcoming. This article proposes a new taxonomy of c...

A Vehicular Ad-Hoc Networks (VANETs) is the technology that uses moving cars as nodes in a network to create a mobile network. VANETs turn every participating car into a wireless router, allowing cars of each other to connect and create a network with a wide range. VANETs are developed for enhancing the driving safety and comfort of automotive users. The VANETs can provide wide variety of servi...
