Experimental Kohonen Neural Network Implemented in CMOS 0.18μm Technology

In this paper, we present an experimental current-mode Kohonen neural network (KNN) implemented in a CMOS 0.18 μm process. The network contains four output neurons. Each neuron has three analog weights related to three inputs. The presented KNN has been re ...

Diffusion Least-Mean Squares Over Adaptive Networks: Formulation and Performance Analysis

Ali H. Sayed

We formulate and study distributed estimation algorithms based on diffusion protocols to implement cooperation among individual adaptive nodes. The individual nodes are equipped with local learning abilities. They derive local estimates for the parameter o ...

Accounting for congestion and spillbacks in fixed-time traffic signal optimization: an analytical queueing model approach

Michel Bierlaire, Carolina Osorio Pizano

We present and analyze a new aggregate model of urban traffic. The objective is to analytically capture the correlation between the different components of the network while maintaining a tractable model that can be used in an optimization framework. Exist ...

A Simulation Model for Wireless Sensor Networks Based on TOSSIM

Giovanni De Micheli, David Atienza Alonso, Francisco Javier Rincon Vallejos, Alexandru Emilian Susu

Wireless Sensor Networks (WSNs) are composed of a large number of very small devices used for biomedical or environmental monitoring applications. These devices measure various natural processes at different locations, and cooperate in order to aggregate t ...

Signal Processing Challenges in Distributed Stream Processing Systems

Pascal Frossard

Distributed stream processing represents a novel computing paradigm where data, sensed externally and possibly preprocessed, is pushed asynchronously to various connected computing devices with heterogeneous capabilities for processing. It enables novel ap ...

Failure Location in Transparent Optical Networks: The Asymmetry Between False and Missing Alarms

Patrick Thiran, Xuan Hung Nguyen

Failure location in transparent optical networks is difficult because of the large amount of alarms that a failure can trigger and because of corrupted alarms. One problem that network operators often face is how to set the thresholds in monitoring devices ...

SensorScope: Experiences with a Wireless Building Monitoring Sensor Network

Martin Vetterli, Henri Julien Dubois-Ferrière, Thomas Schmid

This paper reports on our experience with the implementation, deployment, and operation of SensorScope, an indoor environmental monitoring network. Nodes run on standard TinyOS components and use B-MAC for the MAC layer implementation. The main component o ...

HATS: Hierarchical Adaptive Transmission Scheduling for Multi-Application Adaptation

Willy Zwaenepoel

Applications running on a mobile wireless device most be able to adapt gracefully to limited and fluctuating network resources. When multiple applications run on the same device, control over bandwidth scheduling becomes fundamental in order to coordinate ...

Joint Source/FEC Rate Selection for Quality-Optimal MPEG-2 Video Delivery

Pascal Frossard

This paper deals with the optimal allocation of MPEG-2 encoding and media-independent Forward Error Correction (FEC) rates under a total given bandwidth. The optimality is defined in terms of minimum perceptual end-to-end distortion given a set of video an ...
