Wireless Sensor Network (WSN) is an infrastructure-less wireless network that is deployed in a large number of wireless sensors in an ad-hoc manner that is used to monitor the system, physical or environmental conditions. It can be used for processing, analysis, storage, and mining of the data.WSN can accommodate new devices in the network any time with ease.A wireless sensor network consists of spatially distributed wireless devices which use sensors for monitoring physical and environment conditions.WSN applications are used in the various fields. Some of the WSN applications are area monitoring, air pollution monitoring, health care, water quality monitoring, industrial monitoring, landslide detection, natural disaster prevention.
