Smooth and Fast Rate Adaptation Mechanism (SFRAM) for TCP-Friendly Internet Video
- Proceedings of the International Packet Video Workshop
, 2000
"... A new rate adaptation mechanism based on the TCP-throughput equation and tailored to the Internet video transmission is presented in this paper. The proposed scheme not only achieves TCP-friendliness but also provides a smooth and fast rate adaptation mechanism (SFRAM) for Internet video delivery. B ..."

A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks
, 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
RAP: An End-to-end Rate-based Congestion Control Mechanism for Realtime Streams in the Internet
"... 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 ..."

traffic. Unfairness to TCP traffic is directly determined by how TCP diverges from the AIMD algorithm. Basic RAP behaves in a TCPfriendly fashion in a wide range of likely conditions, but we also devised a fine-grain rate adaptation mechanism to extend this range further. Finally, we show that deploying

Greedy Randomized Adaptive Search Procedures
, 2002
"... GRASP is a multi-start metaheuristic for combinatorial problems, in which each iteration consists basically of two phases: construction and local search. The construction phase builds a feasible solution, whose neighborhood is investigated until a local minimum is found during the local search phas ..."

solution construction mechanisms and techniques to speed up the search are also described: Reactive GRASP, cost perturbations, bias functions, memory and learning, local search on partially constructed solutions, hashing, and filtering. We also discuss in detail implementation strategies of memory
An Adaptive Energy-Efficient MAC Protocol for Wireless Sensor Networks
- 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 ..."

A Fast File System for UNIX
- ACM Transactions on Computer Systems

"... A reimplementation of the UNIX file system is described. The reimplementation provides substantially higher throughput rates by using more flexible allocation policies that allow better locality of reference and can be adapted to a wide range of peripheral and processor characteristics. The new file ..."

Equation-based congestion control for unicast applications
- SIGCOMM '00
, 2000
"... This paper proposes a mechanism for equation-based congestion control for unicast traffic. Most best-effort traffic in the current Internet is well-served by the dominant transport protocol, TCP. However, traffic such as best-effort unicast streaming multimedia could find use for a TCP-friendly cong ..."

-friendly congestion control mechanism that refrains from reducing the sending rate in half in response to a single packet drop. With our mechanism, the sender explicitly adjusts its sending rate as a function of the measured rate of loss events, where a loss event consists of one or more packets dropped within a
