MultiChord: A Resilient Namespace Management Protocol
(2004-02-19)
MultiChord is a new variant of the Chord namespace management algorithm [7] that includes lightweight mechanismsfor accommodating a limited rate of change, specifically, process joins and failures. This paper describes ...
GeoQuorums: Implementing Atomic Memory in Mobile Ad Hoc Networks
(2004-02-25)
We present a new approach, the GeoQuorums approach, for implementing atomic read/write shared memoryin mobile ad hoc networks. Our approach is based on associating abstract atomic objects with certain geographiclocations. ...
Virtual Mobile Nodes for Mobile Ad Hoc Networks
(2004-02-26)
One of the most significant challenges introduced by mobile networks is the difficulty in coping withthe unpredictable movement of mobile nodes. If, instead, the mobile nodes could be programmed totravel through the world ...
Enhancing Availability and Security Through Failure-Oblivious Computing
(2004-02-06)
We present a new technique, failure-oblivious computing,that enables programs to continue to execute through memoryerrors without memory corruption. Our safe compilerfor C inserts checks that dynamically detect invalid ...
REED: Robust, Efficient Filtering and Event Detection in Sensor Networks
(2004-03-22)
This paper presents an algorithm for handling many types of filters insensor networks that cannot be expressed using a simple predicate.Specifically, the action of the filter may be predicated on sensor produceddata where ...
Realistic Modeling of Simple and Complex Cell Tuning in the HMAXModel, and Implications for Invariant Object Recognition in Cortex
(2004-07-27)
Riesenhuber \& Poggio recently proposed a model of object recognitionin cortex which, beyond integrating general beliefs about the visualsystem in a quantitative framework, made testable predictions aboutvisual processing. ...
NIRA: A New Internet Routing Architecture
(2004-10-14)
The present Internet routing system faces two challengingproblems. First, unlike in the telephone system, Internet users cannotchoose their wide-area Internet service providers (ISPs) separatelyfrom their local access ...
EpiChord: Parallelizing the Chord Lookup Algorithm with Reactive Routing State Management
(2004-08-13)
EpiChord is a DHT lookup algorithm that demonstrates that we canremove the O(log n)-state-per-node restriction on existing DHTtopologies to achieve significantly better lookup performance andresilience using a novel reactive ...
Botz-4-Sale: Surviving Organized DDoS Attacks that Mimic Flash Crowds
(2004-10-22)
Recent denial of service attacks are mounted by professionalsusing Botnets of tens of thousands of compromisedmachines. To circumvent detection, attackers areincreasingly moving away from pure bandwidth oods toattacks ...
Early Sketch Processing with Application in HMM Based Sketch Recognition
(2004-07-28)
Freehand sketching is a natural and crucial part of everyday humaninteraction, yet is almost totally unsupported by current user interfaces. With the increasing availability of tablet notebooks and pen based PDAs, sketchbased ...
