Controlling the Mobility of Multiple Data Transport Ferries in a Delay-Tolerant Network

by Wenrui Zhao, Mostafa Ammar, Ellen Zegura - in IEEE INFOCOM , 2005
"... combine both communication and mobility capabilities. With mobility in devices, we envision a new class of proactive networks that are able to adapt themselves, via physical movement, to meet the needs of applications. To fully realize these opportunities, effective control of device mobility and th ..."

and the interaction between devices is needed. In this paper, we consider the Message Ferrying (MF) scheme which exploits controlled mobility to transport data in delay-tolerant networks, where end-to-end paths may not exist between nodes. In the MF scheme, a set of special mobile nodes called message ferries

Dryad: Distributed Data-Parallel Programs from Sequential Building Blocks

by Michael Isard, Mihai Budiu, Yuan Yu, Andrew Birrell, Dennis Fetterly - In EuroSys , 2007
"... Dryad is a general-purpose distributed execution engine for coarse-grain data-parallel applications. A Dryad applica-tion combines computational “vertices ” with communica-tion “channels ” to form a dataflow graph. Dryad runs the application by executing the vertices of this graph on a set of availa ..."

simultaneously on multi-ple computers, or on multiple CPU cores within a computer. The application can discover the size and placement of data at run time, and modify the graph as the computation pro-gresses to make efficient use of the available resources. Dryad is designed to scale from powerful multi-core sin

The Performance of TCP/IP for Networks with High Bandwidth-Delay Products and Random Loss.

by Member, IEEE T V Lakshman , Senior Member, IEEE Upamanyu Madhow - IEEE/ACM Trans. Networking, , 1997
"... Abstract-This paper examines the performance of TCP/IP, the Internet data transport protocol, over wide-area networks (WANs) in which data traffic could coexist with real-time traffic such as voice and video. Specifically, we attempt to develop a basic understanding, using analysis and simulation, ..."

Learning and inferring transportation routines

by Lin Liao, Dieter Fox, Henry Kautz , 2004
"... This paper introduces a hierarchical Markov model that can learn and infer a user’s daily movements through the community. The model uses multiple levels of abstraction in order to bridge the gap between raw GPS sensor measurements and high level information such as a user’s mode of transportation ..."

An Integrated Congestion Management Architecture for Internet Hosts

by Hari Balakrishnan, Hariharan S. Rahul, Srinivasan Seshan - In Proc. ACM SIGCOMM , 1999
"... This paper presents a novel framework for managing network congestion from an end-to-end perspective. Our work is motivated by several trends in traffic patterns that threaten the long-term stability of the Internet. These trends include the use of multiple independent concurrent flows by Web app ..."
Abstract - Cited by 295 (24 self) - Add to MetaCart
integrates congestion management across all applications and transport protocols. The CM maintains congestion parameters and exposes an API to enable applications to learn about network characteristics, pass information to the CM, and schedule data transmissions. Internally, it uses a stable rate

Performance of Reliable Transport Protocol over IEEE 802.11 Wireless LAN: Analysis And Enhancement

by Haitao Wu, Yong Peng, Keping Long, Shiduan Cheng, Jian Ma , 2002
"... EEE 802.11 Medium Access Control(MAC) is proposed to support asynchronous and time bounded delivery of radio data packets in infrastructure and ad hoc networks. The basis of the IEEE 802.11 WLAN MAC protocol is Distributed Coordination Function(DCF), which is a Carrier Sense Multiple Access with Col ..."

Closing the gap in the capacity of wireless networks via percolation theory

by Massimo Franceschetti, Olivier Dousse, David N. C. Tse, Patrick Thiran - IEEE TRANS. INFORMATION THEORY , 2007
"... An achievable bit rate per source–destination pair in a wireless network of � randomly located nodes is determined adopting the scaling limit approach of statistical physics. It is shown that randomly scattered nodes can achieve, with high probability, the same Ia � � transmission rate of arbitrari ..."
Abstract - Cited by 238 (8 self) - Add to MetaCart
theory ensures that crossing paths form in the transition region between these two extreme scenarios. Nodes along these paths are used as a backbone, relaying data for other nodes, and can transport the total amount of information generated by all the sources. A lower bound on the achievable bit rate

A Reliable Dissemination Protocol for Interactive Collaborative Applications

by Rajendra Yavatkar, James Griffioen, Madhu Sudan , 1995
"... The widespread availability of networked multimedia workstations and PCs has caused a significant interest in the use of collaborative multimedia applications. Examples of such applications include distributed shared whiteboards, group editors, and distributed games or simulations. Such applications ..."
Abstract - Cited by 235 (10 self) - Add to MetaCart
. Such applications often involve many participants and typically require a specific form of multicast communication called dissemination in which a single sender must reliably transmit data to multiple receivers in a timely fashion. This paper describes the design and implementation of a reliable multicast transport
