Optimizing UDP-based Protocol Implementations

by unknown authors
"... Abstract—Because of the poor performance of standard TCP over long distance high-speed networks and the practical difficulty in deploying kernel TCP variants, UDP-based transport protocols are often used for bulk data transfer. However, writing a transport protocol from scratch is not an easy job. O ..."

XORs in the air: practical wireless network coding

by Sachin Katti, Hariharan Rahul, Wenjun Hu, Dina Katabi, Muriel Médard, Jon Crowcroft - In Proc. ACM SIGCOMM , 2006
"... This paper proposes COPE, a new architecture for wireless mesh networks. In addition to forwarding packets, routers mix (i.e., code) packets from different sources to increase the information content of each transmission. We show that intelligently mixing packets increases network throughput. Our de ..."

NeXt generation/dynamic spectrum access/cognitive Radio Wireless Networks: A Survey

by Ian F. Akyildiz, Won-Yeol Lee, Mehmet C. Vuran, Shantidev Mohanty - COMPUTER NETWORKS JOURNAL (ELSEVIER , 2006
"... Today's wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited availabl ..."
Abstract - Cited by 746 (15 self) - Add to MetaCart
functions such as spectrum management, spectrum mobility and spectrum sharing are explained in detail. The influence of these functions on the performance of the upper layer protocols such as routing and transport are investigated and open research issues in these areas are also outlined. Finally, the cross

Xbox Live

"... The convergence of games and online social platforms is an exploding phenomena. The continued success of social games hinges critically on the ability to deliver smooth and highly-interactive experiences to end-users. However, it is extremely challenging to satisfy the stringent performance requirem ..."

protocol TCP, currently being used in the game, cannot ensure concurrent messaging. We develop a new UDP-based transport protocol, named Pangolin. The core of Pangolin is an adaptive decision making engine derived from the Markov Decision Process theory. The engine optimally controls the transmission

Event-to-Sink Reliable Transport in Wireless Sensor Networks

by Özgür B. Akan, Ian F. Akyildiz - IEEE/ACM Trans. Networking , 2005
"... Abstract—Wireless sensor networks (WSNs) are event-based systems that rely on the collective effort of several microsensor nodes. Reliable event detection at the sink is based on collective information provided by source nodes and not on any individual report. However, conventional end-to-end reliab ..."

in WSN has not been studied from this perspective before. In order to address this need, a new reliable transport scheme for WSN, the event-to-sink reliable transport (ESRT) protocol, is presented in this paper. ESRT is a novel transport solution developed to achieve reliable event detection in WSN

Improving the Performance of Reliable Transport Protocols in Mobile Computing Environments

by Ramon Caceres, Liviu Iftode - IEEE Journal on Selected Areas in Communications , 1994
"... We explore the performance of reliable data communication in mobile computing environments. Motion across wireless cell boundaries causes increased delays and packet losses while the network learns how to route data to a host's new location. Reliable transport protocols like TCP interpret these ..."

An Active Service Framework and its Application to Real-time Multimedia Transcoding

by Elan Amir, Steven McCanne, Randy Katz , 1998
"... Several recent proposals for an "active networks" architecture advocate the placement of user-defined computation within the network as a key mechanism to enable a wide range of new applications and protocols, including reliable multicast transports, mechanisms to foil denial of service at ..."

Paper Design and Development of a UDP-Based Connection-Oriented Multi-Stream One-to-Many Communication Protocol

by Valentin Stanciu, Mugurel Ionut ̧ Andreica, Vlad Olaru
"... Abstract—A communication protocol is a set of rules defined formally that describes the format of digital messages and the rules for exchanging those messages in or between comput-ing systems. The Internet Protocol Suite used for commu-nications throughout the Internet uses encapsulation to pro-vide ..."

ATP: A Reliable Transport Protocol for Ad-hoc Networks

by Karthikeyan Sundaresan, Vaidyanathan Anantharaman, Hung-Yun Hsieh, Raghupathy Sivakumar , 2003
"... Existing works have approached the problem of reliable transport in ad-hoc networks by proposing mechanisms to improve TCP's performance over such networks. In this paper we show through detailed arguments and simulations that several of the design elements in TCP are fundamentally inappropriat ..."
