Wireless sensor networks (WSNs) refer to networks of spatially dispersed and dedicated sensors that monitor and record the physical conditions of the environment and forward the collected data to a central location. WSNs can measure environmental conditions such as temperature, sound, pollution levels, humidity and wind.
Most underwater sensor networks choose acoustics as the medium for wireless transmission. [14] Electromagnetic waves offer great merits for transmission in special underwater environments. [ 14 ] Applications for subsea wireless sensor technologies can include subsea wireless sensor networks (WSN) for production monitoring, [ 13 ] or oil and ...
Wireless sensor network is a new paradigm in designing fault tolerant mission critical systems, to enable varied applications like threat detection, environmental monitoring, traditional sensing and actuation and much more. It is an emerging area of inter-disciplinary research between people in the electrical engineering, computer science, and ...
Energy cost is a major limitation for WSN requiring the need for energy efficient networks and processing. One of major energy costs in WSN is the energy spent on communication between nodes and it is sometimes desirable to only send data to a gateway node when an event of interest is triggered at a sensor. Sensors will then only open ...
Location estimation in wireless sensor networks is the problem of estimating the location of an object from a set of noisy measurements. These measurements are acquired in a distributed manner by a set of sensors.
MiWi is a proprietary wireless protocol supporting peer-to-peer, star network connectivity. It was designed by Microchip Technology.MiWi uses small, low-power digital radios based on the IEEE 802.15.4 standard, and is designed for low-power, cost-constrained networks, such as industrial monitoring and control, home and building automation, remote control, wireless sensors, lighting control ...

A recent review discusses various techniques to take smartdust in sensor networks beyond millimeter dimensions to the micrometre level. [ 6 ] The Ultra-Fast Systems component of the Nanoelectronics Research Centre at the University of Glasgow is a founding member of a large international consortium which is developing a related concept: smart ...
