Scitus Academics Emerging Communications For Wireless Sensor Networks by Dong Chin Sun
Wireless sensor networks are deployed in a rapidly increasing number of fields, with uses ranging from healthcare monitoring to industrial and environmental safety, along with new ubiquitous computing devices that are becoming ever more pervasive in our interconnected society. A wireless sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations. Commonly monitored parameters are temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions. A sensor network consists of multiple detection stations called sensor nodes, each of which is small, lightweight and portable. Every sensor node is equipped with a transducer, microcomputer, transceiver and power source. The transducer generates electrical signals based on sensed physical effects and phenomena. The microcomputer processes and stores the sensor output. The transceiver receives commands from a central computer and transmits data to that computer. The power for each sensor node is derived from a battery.
Emerging Communications for Wireless Sensor Networks presents an assortment of exciting progresses in software communication technologies with some novel applications, such as in high altitude systems, ground heat exchangers and body sensor networks. The text discloses up-to-date findings in the spirit of exchanging information and stimulating discussion in the wireless sensor networks community worldwide.
