As Wireless Sensor Networks are evolving in a wide range where high load demands dominate and affects the overall performance of the network, congestion remains a serious problem that has to be tackled effectively. Since the capacity of shared wireless medium is limited, channel contention and network congestion can be experienced during the operation of the network. In this paper, a new cross-...

In this paper, the design of explicit rate-based congestion control in high speed communication networks is considered. At a bottleneck node, there are multiple best-effort sources competing with other high priority cross traffic sources. The goal of congestion control is to achieve high link utilization, low packet loss, low delay, and fairness among the best-effort sources. In this paper, the...

Emerging standardization of Geo Mobile Radio (GMR-1) for satellite system is having strong resemblance to terrestrial GSM (Global System for Mobile communications) at the upper protocol layers and TCP (Transmission Control Protocol) is one of them. This space segment technology as well as terrestrial technology, is characterized by periodic variations in communication properties and coverage ca...

The problem of controlling congestion in high-speed communication networks is introduced. An easy-to-implement explicit rate congestion control algorithm is presented, and its stability properties are discussed. The algorithm is decentralized and is robust to network delays. Furthermore, it does not require per-flow information. It is shown that the network level implementation of this algorith...

Satellite communication systems are the means of realizing a global broadband integrated services digital network. Due to the statistical nature of the integrated services traac, the resulting rate uctuations and burstiness render congestion control a complicated, yet indispensable function. The long propagation delay of the earth-satellite link further imposes severe demands and constraints on...

The demand for Internet based services has exploded over the last decade. Many organizations use the Internet and particularly the World Wide Web as their primary medium for communication and business. This phenomenal growth has dramatically increased the performance requirements for the Internet. To have a high performance Internet, a good congestion control system is essential for it. The cur...

Congestion control is a fundamental building block in packet switching networks such as the Internet due to the fact that communication resources are shared. It has been shown that the plant dynamics is essentially made of an integrator plus time delay and that a proportional controller plus a Smith predictor defines a simple and effective controller. It has been also shown that the today runni...

Large propagation-bandwidthproducts and diverse traffic characteristics have made traditional network congestion control and bandwidth management schemes less effective in high speed networks such as ATM. Furthermore, heterogeneities in ATM network size and the services offered must be considered in the development of effective congestion and resource control disciplines. New mechanisms for tra...

Active queue control aims to improve the overall communication network throughput, while providing lower delay and small packet loss rate. The basic idea is to actively trigger packet dropping (or marking provided by explicit congestion notification (ECN)) before buffer overflow. In this paper, two artificial neural networks (ANN)-based control schemes are proposed for adaptive queue control in...

Since the Wireless Sensor Networks (WSN) use battery powered, the system design at all level emphasizes energy-efficiency. Sensor with cross-layer design improves the network in terms of energy utilization.Cross-layer approach blends common protocol layerfunctionalities into a single module. However, most of the cross-layered based solutions have a limited scope or give only the analytical resu...
