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.
The basic ULE wireless network uses a “star network topology”; i.e. there is one main device, called “base”, which controls the network; the “base” is wirelessly connected to “nodes”, which usually are devices with dedicated functions, such as sensors, remote controls, actuators, smart meters, etc.
Adaptive Time Slotted Channel Hopping for Wireless Sensor Networks (PDF) Tavakoli, Rasool; Nabi, Majid; Basten, Twan; Goossens, Kees (2015), "Enhanced Time-Slotted Channel Hopping in WSNs Using Non-intrusive Channel-Quality Estimation", 2015 IEEE 12th International Conference on Mobile Ad Hoc and Sensor Systems , pp. 217– 225, doi : 10.1109 ...
Some of these technologies include standards such as ANT UWB, Bluetooth, Zigbee, and Wireless USB. 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 ...
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 ...
A mobile wireless sensor network (MWSN) [1] can simply be defined as a wireless sensor network (WSN) in which the sensor nodes are mobile. MWSNs are a smaller, emerging field of research in contrast to their well-established predecessor.
Low-energy adaptive clustering hierarchy ("LEACH") [1] is a TDMA-based MAC protocol which is integrated with clustering and a simple routing protocol in wireless sensor networks (WSNs). The goal of LEACH is to lower the energy consumption required to create and maintain clusters in order to improve the life time of a wireless sensor network.
ANT (originates from Adaptive Network Topology) is a proprietary (but open access) multicast wireless sensor network technology designed and marketed by ANT Wireless (a division of Garmin Canada). [1] It provides personal area networks (PANs), primarily for activity trackers. ANT was introduced by Dynastream Innovations in 2003, followed by the ...
