Adaptive Distributed Algorithms for Power-Efficient Data Gathering in Sensor Networks

In this work, we consider the problem of designing adaptive distributed processing algorithms in large sensor networks that are efficient in terms of minimizing the total power spent for gathering the spatially correlated data from the sensor nodes to a si ...

Scaling Laws for Correlated Data Gathering

Martin Vetterli, Razvan Cristescu

Consider a set of correlated sources located at the nodes of a network, and a sink to which the data from all the sources has to arrive. We address the minimization of a separable joint communication cost function given by the product [rate]

Beyond 1-Safety and 2-Safety for replicated databases: Group-Safety

André Schiper, Matthias Wiesmann

In this paper, we study the safety guarantees of group communication-based database replication techniques. We show that there is a model mismatch between group communication and database, and because of this, classical group communication systems cannot b ...

A Multimodal Database Framework for Multimedia Meeting Annotations

Stefano Spaccapietra, Hassina Bounif, Oleksandr Drutskyy

The main objective of this paper is to present a flexible annotation management framework for a multimedia database system, applied to meeting recordings. Presented research and development activities are carried out within the scope of the IM2 project in ...

Power-Efficient Sensor Placement and Transmission Structure for Data Gathering under Distortion Constraints

Razvan Cristescu

We consider the joint optimization of sensor placement and transmission structure for data gathering, where a given number of nodes need to be placed in a field such that the sensed data can be recon structed at a sink within specified distortion bounds wh ...

C-JDBC: Flexible Database Clustering Middleware

Willy Zwaenepoel, Emmanuel Cecchet

Large web or e-commerce sites are frequently hosted on clusters. Successful open-source tools exist for clustering the front tiers of such sites (web servers and application servers). No comparable success has been achieved for scaling the backend database ...

Perceptually-tuned grayscale characters based on parametrisable component fonts

Roger Hersch

Our component-based parametrisable font system is a newly developed font description and reproduction technology. It incorporates for each basic character shape a software method responsible for the synthesis of an instance of that character. A given font ...

Performance Comparison of Middleware Architectures for Generating Dynamic Web Content

Willy Zwaenepoel, Sameh Mohamed Elnikety, Emmanuel Cecchet

On-line services are making increasing use of dynamically generated Web content. Serving dynamic content is more complex than serving static content. Besides a Web server, it typically involves a server-side application and a database to generate and store ...

Monitoring of Resource Consumption in Java-based Application Servers

To realize dependable and profitable information and communication systems, computing resources (CPU, memory, network bandwidth) should be taken into account to a much wider extent than they are today. E-commerce infrastructure, such as application servers ...
