End-System Aware, Rate-Adaptive Protocol for Network Transport in LambdaGrid Environments

by Pallab Datta, et al. - SC2006 , 2006
"... Next-generation e-Science applications will require the ability to transfer information at high data rates between distributed computing centers and data repositories. A Lambda-Grid offers dedicated, optical, circuit-switched, point-topoint connections that can be reserved exclusively for such appli ..."

-speed dedicated circuits is of critical importance. We propose the idea of a end-system aware, rate-adaptive protocol for network transport, based on end-system performance monitoring. Our proposed protocol significantly improves the performance of data transfer over LambdaGrids by intelligently adapting

Distributed Utility-Based Rate Adaptation Protocols for Prioritized, Quasi-Elastic Flows

by Sharanya Eswarana, Matthew P. Johnsonb, Archan Misrac, Thomas La Portaa
"... This paper considers rate adaptation for streaming multimedia data in a wireless sen-sor network (WSN) consisting of multiple missions, where each mission subscribes to data streams from multiple sensors, and each sensor’s data is utilized by multiple heteroge-nous missions. We specifically consider ..."

A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks

by Gavin Holland, Nitin H. Vaidya, Paramvir Bahl , 2001
"... Wireless local area networks (W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates. These high rates are possible, in part, through new modulation schemes that are optimized for the channel conditions bring ..."

relatively few proposals for W-LANs. In this paper we present a rate adaptive MAC protocol called the Receiver-Based AutoRate (RBAR) protocol. The novelty of RBAR is that its rate adaptation mechanism is in the receiver instead of in the sender. This is in contrast to existing schemes in devices like

Receiver-driven Layered Multicast

by Steven McCanne, Van Jacobson, Martin Vetterli , 1996
"... State of the art, real-time, rate-adaptive, multimedia applications adjust their transmission rate to match the available network capacity. Unfortunately, this source-based rate-adaptation performs poorly in a heterogeneous multicast environment because there is no single target rate — the conflicti ..."

receiver specifies its level of subscription by joining a subset of the groups. In this paper, we extend the multiple group framework with a rate-adaptation protocol called Receiver-driven Layered Multicast, or RLM. Under RLM, multicast receivers adapt to both the static heterogeneity of link bandwidths

RAP: An End-to-end Rate-based Congestion Control Mechanism for Realtime Streams in the Internet

by Reza Rejaie, Mark Handley, Deborah Estrin
"... End-to-end congestion control mechanisms have been critical to the robustness and stability of the Internet. Most of today’s Internet traffic is TCP, and we expect this to remain so in the future. Thus, having “TCP-friendly” behavior is crucial for new applications. However, the emergence of non-co ..."
Abstract - Cited by 429 (22 self) - Add to MetaCart
-congestion-controlled realtime applications threatens unfairness to competing TCP traffic and possible congestion collapse. We present an end-to-end TCP-friendly Rate Adaptation Protocol (RAP), which employs an additive-increase, multiplicative decrease (AIMD) algorithm. It is well suited for unicast playback of realtime

An Adaptive Energy-Efficient MAC Protocol for Wireless Sensor Networks

by Tijs van Dam, Koen Langendoen - SENSYS'03 , 2003
"... In this paper we describe T-MAC, a contention-based Medium Access Control protocol for wireless sensor networks. Applications for these networks have some characteristics (low message rate, insensitivity to latency) that can be exploited to reduce energy consumption by introducing an active/sleep du ..."

Rate-Adaptive MAC Protocol in High-Rate Personal Area Networks

by Byung-seo Kim, Yuguang Fang, Tan F. Wong - in Proceedings of the IEEE Wireless Communications and Networking Conference (WCNC ’04 , 2004
"... Area Network (HR WPAN) has been standardized by the IEEE 802.15.3 Task Group for communications of consumer electronics and portable communication devices and a final draft standard has been completed. The physical layer in IEEE 802.15.3 standard is designed to achieve data rates of 11-55Mbps. Howev ..."

. However, a MAC protocol in IEEE 802.15.3 standard does not specify the method to choose an appropriate data rate. In this paper, we propose a rate-adaptive Medium Access Control (MAC) protocol for HR WPAN. The data rate for the next transmission is selected by channel prediction based on the currently

Dynamic source routing in ad hoc wireless networks

by David B. Johnson, David A. Maltz - Mobile Computing , 1996
"... An ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. In such an environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its desti ..."

The protocol adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods
