In computer science and telecommunications, wireless sensor networks are an active research area supporting many workshops and conferences, including International Workshop on Embedded Networked Sensors (EmNetS), IPSN, SenSys, MobiCom and EWSN. As of 2010, wireless sensor networks had deployed approximately 120 million remote units worldwide. [8]
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 ...
However, since the wireless sensor node is often placed in a hard-to-reach location, changing the battery regularly can be costly and inconvenient. An important aspect in the development of a wireless sensor node is ensuring that there is always adequate energy available to power the system. The sensor node consumes power for sensing ...
Defense-related sensor networks such as battlefield surveillance, treaty monitoring, transportation monitoring, and scud hunting. Virtual keyboard sensors: by attaching miniature remotes to each fingernail, accelerometers could then sense the orientation and motion of each fingertip, and communicate this data to a computer in a wristwatch.
There is a solution proposed for the analytics of the information referred to as Wireless Sensor Networks. [253] These networks share data among sensor nodes that are sent to a distributed system for the analytics of the sensory data. [254] Another challenge is the storage of this bulk data.
Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks". Nodes typically connect in a star or mesh topology.
A wireless identification and sensing platform (WISP) is an RFID (radio-frequency identification) device that supports sensing and computing: a microcontroller powered by radio-frequency energy. [1] That is, like a passive RFID tag, WISP is powered and read by a standard off-the-shelf RFID reader, harvesting the power it uses from the reader's ...
A sensor node, also known as a mote (chiefly in North America), is a node in a sensor network that is capable of performing some processing [1], gathering sensory information and communicating with other connected nodes in the network. A mote is a node but a node is not always a mote.
