WIRELESS SENSOR NETWORKS - A STUDY

Abstract

Wireless sensor networks (WSN) are spatially distributed autonomous sensors to monitor the
physical or environmental conditions such as temperature, sound, pressure, etc. It is the
collection of large number of sensor nodes in sensor fields. The major application in WSN is
like remote environmental monitoring, detections of forest fire and target tracking. This
environment is particularly in sensors for recent years that are smaller, cheaper and
intelligent. The sensors are associated with wireless interfaces with which the communication
takes place with one another to form a network. This paper discuss about wireless sensor
networks in addition to that it includes some of the fields in radio networks and also provides
new applications for sensing and transferring of information from various environments.
