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

A Rate-Adaptive MAC Protocol for Wireless Networks

by Gavin Holland, Nitin Vaidya, Paramvir Bahl , 2000
"... Wireless local-area networks are becoming increasingly popular. This is due, in part, to the recent availability of devices capable of communicating at data rates approaching that of conventional wired networks. These high rates are made possible through new modulation and coding techniques that dra ..."

A Rate-Adaptive MAC Protocol for Low-Power . . .

by Ruben Merz, Jean-Yves Le Boudec, Jörg Widmer, Božidar Radunović - IN 3RD INTERNATIONAL CONFERENCE ON AD-HOC NETWORKS AND WIRELESS (AD-HOC NOW),JULY , 2004
"... Recent theoretical results show that it is optimal to allow interfering sources to transmit simultaneously, as long as they are outside a well-defined exclusion region around a destination, and to adapt the rate to interference. In contrast, interference from inside the exclusion region needs to ..."

An Extension of Rate-Adaptive MAC Protocol for NS2 Simulator

by Mingzhe Li, Emmanuel Agu
"... The IEEE 802.11 wireless media access standard supports multiple data rates at the physical layer. Moreover, various auto rate adaptation mechanisms at the medium access layer have been proposed to utilize this multi-rate capability by automatically adapting the transmission rate to best match the c ..."

the channel conditions. However, there is little available simulation implementation available for the multi-rate adaptation research purpose. In this project, an extension of rate-adaptive MAC protocol based on the Receiver-Based Auto-Rate (RBAR) was developed to enable the multi-rate simulation in NS2

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

A Rate-adaptive MAC protocol for lowpower ultra-wide band ad-hoc networks

to be controlled. Furthermore, when a source transmits, it should do so at maximum power. Based on these theoretical findings, we propose a cross-layer design of MAC and physical layer and present a fully distributed, rate adaptive MAC protocol for ultra-wide band (UWB) where sources constantly adapt their channel

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 ..."

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
