The majority of nondestructive evaluation (NDE) and structural health monitoring (SHM) techniques have been developed in recognition of the fact that the presence of damage alters structural properties (stiffness, density, damping ratio, energy dissipation, etc.), and hence alters the captured dynamic signatures of the structure such as Lamb wave ...

Sometimes sensors need to be assembled in response to an emergency. Such assemblage might take a variety of forms. At one extreme, sensors might converge on a single point. At the opposite extreme, sensors might fill in the position of a lattice. This paper looks at solutions in between these two extremes, in which sensors converge on several different

As sensor nodes are embedded into physical environments and becoming integral parts of our daily lives, sensor networks will become the important nerve systems that monitor and actuate our physical environments. We define the process of monitoring the status of a sensor network and figuring out the problematic sensor nodes sensor network diagnosis ...

With a continuing improvement in the capabilities of intelligence per unit of energy, we should reconsider the organisation of sensor networks. We contend that solutions should be model-free, locally based and need to be highly dynamic in nature. Here we propose an approach inspired by simulated annealing.

2007 International Symposium on System-on-Chip, 2007
In this paper, we present the sensor network-on-a-chip (SNOC) paradigm for designing robust and energy-efficient systems-on-a-chip (SOC). In this paradigm, computation in the presence of nanometer non-idealities such as process variations, leakage and noise is viewed as an estimation problem. Robust statistical signal processing theory is then employed

Given a set of sensors or cluster of sensors S located at different points or nodes in the ordinary space. Any sensor measures one or more values, such as Temperature. We assume that the information from all sensors at different positions in the space is transmitted to a Gateway node as a probabilistic phenomena, not in a deterministic way.

Interacting with sensor networks
IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004We develop distributed algorithms for sensor networks that respond by directing a target (robot or human) through a region. The sensor network models the event levels sensed across a geographical area, adapts to changes, and guides a moving object incrementally across the network.

Proceedings International Parallel and Distributed Processing Symposium, 2004
The networks considered in this paper consist of tiny energy constrained commodity sensors massively deployed, along with one or more sink nodes providing interface to the outside world. Our contribution is to propose a scalable energy-efficient training protocol for nodes that are initially anonymous, asynchronous and unaware of their locations ...

The confluence of inexpensive wireless communication, computation, and sensing has created a new generation of smart devices. Using tens to thousands of these devices in self-organizing networks has created a new technology referred to as wireless sensor networks. This article gives an overview of the wireless sensor networks.

This introductory paper serves as an overview about the rest of the papers that are contained within this volume. In this article it is presented our vision of the Citizen Sensor Networks as twofold: one where the citizens are passive entities that need to be tracked to understand and optimize better the SmartCities, and the second where the citizens ...
