WSN

Recent advances in semiconductor, networking and material science technologies are driving the ubiquitous deployment of large-scale wireless sensor networks (WSNs). Together, these technologies have combined to enable a new generation…

The Industrial, Scientific, and Medical (ISM) radio frequency spectrum was originally set aside to accommodate mechanical equipment which generated significant radio emissions. At that time, this was limited to microwave ovens, RF…

Providing power is a critical consideration in developing any type of remote communications or wireless sensor network. Implementing an energy harvesting design, along with an energy storage element, can extend the workable life of a…

Wireless Sensor Networks (WSN) are the enabling technology for efficient and inexpensive Precision Agriculture (PA). Prior to PA, farmers had to rely on satellite and aircraft imagery or other map based systems to accurately target…

A critical design element of any wireless sensor network (WSN) is how to power the sensors. Options include providing a self contained power source, an energy storage unit (e.g., battery) and incorporating some method of energy…

The HART protocol for communications in wireless sensor networks (WSN) is aptly referred to as " WirelessHART". This is based on the earlier, wired version of the HART (Highway Addressable Remote Transducer) protocol. Both the HART…

The essential building blocks for wireless sensor networks can be segmented into hardware,  middleware, software, communications protocol, and user interface. This is a simplified representation of a wireless sensor network (WSN),…
