Virtual sensors for control applications
Annual Reviews in Control, 2002Abstract The main goal of a sensing device is to provide reliable, precise, up-to-date and concise information about a process variable, parameter or index, to be used for different monitoring or control purposes. Other than using the basic transducer device, it is also possible to convert a variable into another one which is easier to handle. Modern

A virtual sensor for room detection
IEEE/RSJ International Conference on Intelligent Robots and System, 2003Indoor environments typically consist of sets of connected room-like spaces. We present a local technique that uses range data to detect these spaces during navigation. Our technique includes two parts: segmentation, which isolates room-like spaces and detects when the robot has entered a new one; and feature extraction, which associates each space ...

Proceedings of the 2nd International Conference on Intelligent and Innovative Computing Applications, 2020
Sensorial escalation, heterogeneity, pervasiveness, and increased connectivity have created a haven for cyber-criminals, where potential attacks are being exacerbated on a daily basis. In essence, most automated systems are not built to be able to dynamically detect potential security incidents or to provide digital forensic evidence that could be used

On the Design of Vehicular Virtual Sensors
2017 13th International Conference on Distributed Computing in Sensor Systems (DCOSS), 2017Physical sensors are an important part of control systems, especially vehicular control systems. Sensor readings help drivers to control their vehicles as well as their internal systems while keeping a vehicle stable and running. Currently, a modern luxury car carries hundreds of diverse and precise sensors and not all of them are visible to the driver.

Virtual Sensors for Dynamic Virtual Environments
1st IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing, 2005., 2006This paper proposes a sensor-based mechanism that allows virtual creatures to perceive the environment that surrounds them. We are keen on modeling the behavior of real-life creatures via VR-techniques. Every living creature is endowed by a number of senses, by means of which, the creature is aware of the world around.

Self-organizing virtual macro sensors
ACM Transactions on Autonomous and Adaptive Systems, 2012The future large-scale deployment of pervasive sensor network infrastructures calls for mechanisms enabling the extraction of general-purpose data at limited energy costs. The approach presented in this article relies on a simple algorithm to let a sensor network self-organize a virtual partitioning in correspondence to spatial regions characterized by

A logic approach to virtual sensor networks
Proceedings of the Fourteenth International Database Engineering & Applications Symposium on - IDEAS '10, 2010This paper presents a technique that builds a layer of virtual sensors over a sensor network. The virtual sensors are able to infer and provide data for the physical sensors that do not work. The key assumption of our approach is that the physical quantities sensed by the sensors are related.

Virtualization of wireless sensor PANs would be useful for general purpose networked sensing with application concurrency, for community-based sensor sharing, and for supporting platform heterogeneity as well as robustness. This abstract presents a snapshot of the preliminary design and implementation of a middleware for lightweight sensor network ...

Implementation of virtual sensors for building a sensor-cloud environment
2016 8th International Conference on Communication Systems and Networks (COMSNETS), 2016There has been a recent attempt by the researchers to leverage the widespread usage of small sensor nodes and integrate them with cloud technology for building an environment for Internet of Things. While some applications have already been developed to transmit the data from physical sensors to cloud environment, we propose to create and include ...

Virtual Sensors: Abstracting Data from Physical Sensors
2006 International Symposium on a World of Wireless, Mobile and Multimedia Networks(WoWMoM'06), 2006Sensor networks are becoming increasingly pervasive. Existing methods of aggregation in sensor networks offer mostly standard mathematical operators over homogeneous data types. In this paper, we instead focus on supporting emerging scenarios in which applications will need to extract abstracted measurements from diverse sets of sensor network nodes ...
