Adequate sensor placement is a necessary condition for efficient fault diagnosis systems. Sensor placement for diagnosability consists in studying where to place sensors to satisfy diagnosability specifications. This paper presents a method based on a structural analysis that takes into account diagnosability specifications. It is based on the study of properties of structural matrices and on t...

In-network query processing is critical for reducing network traffic when accessing and manipulating sensor data. It requires placing a tree of query operators such as filters and aggregations but also correlations onto sensor nodes in order to minimize the amount of data transmitted in the network. In this paper, we show that this problem is a variant of the task assignment problem for which p...

Mining operations can produce highly localized, low intensity earthquakes that are referred to as microseismic events. Monitoring of microseismic events is useful in predicting and comprehending hazards, and in evaluating the overall performance of a mine design. A robust localization algorithm is used to estimate the source position of the microseismic event by selecting the hypothesized sourc...

Movement data from athletes are useful to quantify performance or more specifically the workload. Inertial measurement units (IMUs) sensors body movements. Sensor placement on human is still an open question that this paper focuses on. A method develops synthesized inertial proposed for determining optimal placement. Comparison between virtual and real achieved. Training motion recognition algo...

In this paper, the problem of configuration selection i.e. sensor/actuator placement for piecewise affine (PWA) systems subject to both sensor and actuator faults is considered. A method is proposed that provides a tool for the design phase to decide about the optimal placement of sensor/actuators where the reconfigurability of the system subject to sensor and actuator faults is also taken into...

We simulated a sensor network that detects and tracks the release of harmful airborne contaminants in an urban environment. The simulation determines sensor placement in that environment. The effort required integration of models from computational fluid dynamics (CFDs), combinatorial optimization, and population mobility dynamics. These CFD models, coupled with population mobility models, faci...

Wireless Sensor Network (WSN) is a technology, which has great invention for public and the defense. The wireless sensor communication technology allows random participation of sensor nodes with particular applications to take part in the network, which results in most of the uncovered simulation area, where fewer nodes are located at far distances. The drawback of such network would be, additi...

This paper presents a new unified approach for solving diagnosis and sensor placement problems. In previous works [3], we have shown that the main computational challenge in model-based diagnosis, that is, the calculation of minimal diagnosis set, can be represented as the solution of the Hitting Set Problem. We have also shown that this calculation can be mapped onto the Integer Programming pr...
