Smart Environments
From Wikipedia, the free encyclopedia
Smart environments is a technological concept that, according to Mark Weiser is "a physical world that is richly and invisibly interwoven with sensors, actuators, displays, and computational elements, embedded seamlessly in the everyday objects of our lives, and connected through a continuous network" [1]

[edit] Introduction
Smart environments are envisioned as the byproduct of pervasive computing and the availability of cheap computing power, making human interaction with the system a pleasant experience.
[edit] Definition
Cook and Sajal [1], define Smart environment as "a small world where all kinds of smart devices are continuously working to make inhabitants' lives more comfortable." Smart environments aim to satisfy the experience of individuals from every environment, by replacing the hazardous work, physical labor, and repetitive tasks with automated agents.
[edit] Features
Smart environments are broadly classified to have the following features
- Remote control of devices, like power line communication systems to control devices.
- Device Communication, using middleware, and Wireless communication to form a picture of connected environments.
- Information Acquisition/Dissemination from sensor networks
- Enhanced Services by Intelligent Devices
- Predictive and Decision-Making capabilities
[edit] Technologies
To build a smart environment, involves technologies of
- Wireless communication
- Algorithm design, Signal Prediction & Classification, Information theory,
- Multilayered Software Architecture, Corba, middleware
- Speech recognition
- Image processing, Image recognition
- Sensors design, calibration, Motion detection, temperature, pressure sensors, accelerometers
- Adaptive control, Kalman filters
- Computer Networking
- Parallel processing
- Operating Systems
[edit] Existing projects
The MavHome (Managing an Adaptive Home) project at UT Arlington , is a smart environment-lab with state of the art, algorithms and protocols, used to provide a customized, and personal environment to the users of this space. The MavHome project, in addition to providing a safe environment, MavHome wants to reduce the energy consumption of the inhabitants [2].
