A Survey Report on Wireless Sensor Network

Wireless Sensor Network (WSN) is the combination of various sensing nodes. WSN is used to produce meaningful information from raw local data collected by each sensor. The characteristics of sensor network create many new and existing application areas for remote sensing. Also now a day there is much application in many field and WSN faces security challenges so I have discussed it with architecture of WSN. With advancement in WSN, small and low cost sensor nodes become available, which have capabilities of wireless communication, sensing various types of environmental conditions and data processing. Now a day, we are living in advance technology environment, which has a great advantage on every person life. Wireless sensor network is one of them which is the collection of nodes organized into a cooperative network and in every node consist of processing capability, and may contains  multiple types of memory. In this paper there is review of introduction of Wireless Sensor Network and its application in various fields with security challenges. Also I have discussed various factors that affect the sensor network design. Wireless Sensor Network has tremendous advantages in the worlds which makes every person life much easier and also have various applications.
