A New Approach for Data Filtering in Wireless Sensor Networks

Wireless Sensor Network has encouraged researchers to broaden up the field by critically evaluating and realizing its capabilities in various application areas. With every innovation there comes along lot of challenges. Conceiving an idea of implementing wireless sensor network has shown many challenges, i.e., node deployment, data clustering, data aggregation, energy efficiency, lifetime improvement, etc. In this paper, we have proposed a filtering scheme at the sensor/relay node which filters out the spurious and redundant data and is applicable both for critical as well as noncritical applications. The proposed approach shows promising results by filtering out useless data. This technique improves energy efficiency and network lifetime of the network.
