Discovering dependencies for network management

by Paramvir Bahl, Paul Barham, Richard Black, Ranveer Chandra, Moises Goldszmidt, Rebecca Isaacs, Srikanth Kandula, Lun Li, John Maccormick, David A. Maltz, Richard Mortier, Mike Wawrzoniak, Ming Zhang - IN PROC. V HOTNETS WORKSHOP , 2006
"... This paper presents the Leslie Graph, a simple yet powerful abstraction describing the complex dependencies between network, host and application components in modern networked systems. It discusses challenges in the discovery of Leslie Graphs, their uses, and describes two alternate approaches to t ..."

Capacity of Ad Hoc Wireless Networks

by Jinyang Li, Charles Blake, Douglas S. J. De Couto, Hu Imm Lee, Robert Morris
"... Early simulation experience with wireless ad hoc networks suggests that their capacity can be surprisingly low, due to the requirement that nodes forward each others’ packets. The achievable capacity depends on network size, traffic patterns, and detailed local radio interactions. This paper examine ..."

Using Bayesian networks to analyze expression data

by Nir Friedman, Michal Linial, Iftach Nachman - Journal of Computational Biology , 2000
"... DNA hybridization arrays simultaneously measure the expression level for thousands of genes. These measurements provide a “snapshot ” of transcription levels within the cell. A major challenge in computational biology is to uncover, from such measurements, gene/protein interactions and key biologica ..."

biological features of cellular systems. In this paper, we propose a new framework for discovering interactions between genes based on multiple expression measurements. This framework builds on the use of Bayesian networks for representing statistical dependencies. A Bayesian network is a graph-based model

Routing Techniques in Wireless Sensor Networks: A Survey

by Jamal N. Al-karaki, Ahmed E. Kamal - IEEE WIRELESS COMMUNICATIONS , 2004
"... Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing, power management, and data dissemination protocols have been specifically designed for WSNs where energy awareness is an essential design issue. The focus, howeve ..."

Managing Update Conflicts in Bayou, a Weakly Connected Replicated Storage System

by Douglas Terry, Marvin Theimer, Karin Petersen, Alan Demers, Mike Spreitzer, Carl Hauser - In Proceedings of the Fifteenth ACM Symposium on Operating Systems Principles , 1995
"... Bayou is a replicated, weakly consistent storage system designed for a mobile computing environment that includes portable machines with less than ideal network connectivity. To maximize availability, users can read and write any accessible replica. Bayou's design has focused on supporting apph ..."

Finding structure in time

by Jeffrey L. Elman - COGNITIVE SCIENCE , 1990
"... Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather than explicitly (as in a spatial representation). The current report develops a pro ..."

of prior internal states. A set of simulations is reported which range from relatively simple problems (temporal version of XOR) to discovering syntactic/semantic features for words. The networks are able to learn interesting internal representations which incorporate task demands with memory demands

The Cricket Location-Support System

by Nissanka B. Priyantha, Anit Chakraborty, Hari Balakrishnan , 2000
"... This paper presents the design, implementation, and evaluation of Cricket, a location-support system for in-building, mobile, locationdependent applications. It allows applications running on mobile and static nodes to learn their physical location by using listeners that hear and analyze informatio ..."

Experimental Queueing Analysis with Long-Range Dependent Packet Traffic

by Ashok Erramilli, Onuttom Narayan, Walter Willinger - IEEE/ACM Transactions on Networking , 1996
"... Recent traffic measurement studies from a wide range of working packet networks have convincingly established the presence of significant statistical features that are characteristic of fractal traffic processes, in the sense that these features span many time scales. Of particular interest in packe ..."

Impact of Radio Irregularity on Wireless Sensor Networks

by Gang Zhou, Tian He, Sudha Krishnamurthy, John A. Stankovic - in MobiSYS ’04: Proceedings of the 2nd international conference on Mobile systems, applications, and services , 2004
"... In this paper, we investigate the impact of radio irregularity on the communication performance in wireless sensor networks. Radio irregularity is a common phenomenon which arises from multiple factors, such as variance in RF sending power and different path losses depending on the direction of prop ..."

A Gossip-Style Failure Detection Service

by Robbert Van Renesse, Yaron Minsky, Mark Hayden , 1998
"... Failure Detection is valuable for system management, replication, load balancing, and other distributed services. To date, Failure Detection Services scale badly in the number of members that are being monitored. This paper describes a new protocol based on gossiping that does scale well and provide ..."

and provides timely detection. We analyze the protocol, and then extend it to discover and leverage the underlying network topology for much improved resource utilization. We then combine it with another protocol, based on broadcast, that is used to handle partition failures.
