WSN consists of spatially distributed autonomous sensors used to monitor physical or environmental conditions, such as sound, pressure, temperature etc. and to commonly pass their data through the network to a primary location. The advancement of wireless sensor networks was motivated by military applications such as battlefield surveillance; today such networks are used in many industrial applications and consumer applications, such as machine health observing, industrial process observing and control, and so on. Sensor nodes are capable of sensing and transmitting. They collect huge amount of data in a highly decentralized manner. The data collected contain all the information about the region. But sometimes users need only the specific information and for them rest of the information is treated as irrelevant. So, here the authors filter out that irrelevant data for the benefit of the users.
