Achieving Efficient Security and less Energy Consumption using Node Energy in WSN

Wireless Sensor Networks (WSN), an element of pervasive computing, are presently being used on a large scale to monitor real-time environmental status Designing cost-efficient, secure network protocols for Wireless Sensor Networks (WSNs) is a challenging problem because sensors are resource-limited wireless devices. Sensor devices are the power consumption devices to achieve low power consumption and high security we need to avoid the rekeying ,stale keys, reducing the false data from malicious node and dynamic energy based keying technology were used. Since the communication cost is the most dominant factor in a sensor’s energy consumption, we introduce an Efficient Node Energy Based Encoding (ENEBE) and Filtering of False data Injection. ENEBE and FFDI is able to efficiently detect and filter false data injected into the network by malicious from outside. The Efficient Node Energy Based Encoding (ENEBE) and Filtering of False data Injection (FFDI) consists of two operational modes.
