Excluding compromised node by tracing false data injected messages in Wireless Sensor Network

Wireless Sensor Network (WSN) is a collection of sensor nodes that involve in gathering of happenings from a nodes´ surrounding. They help in supervising all the mission critical applications instead of depending on humans in monitoring cynical areas. Sensor nodes play a important role in alerting us any distinct changes that occur in the sited area and is prone to innumerous attacks. These attacks damage trust with the received data from a sensor node. One such type of attack is the false data injection attack. The message is forged by the adversary, not detected by the forwarding nodes as false information. Compromised node is the origin of false data to be injected in to the WSN. The proposed work discards the false data injected message from the network. This issue of compromised node is handled by the detection and elimination of it from causing further damage to the network by incorporating Elliptical Curve Cryptography (ECC) technique for data authentication to any message received. A node involved in sensing requires a high range of sensing power. But sensor nodes have limited energy and this is a battle for all technicians in creating any inventions that suits this constraint. The proposed scheme provides safety and reliability over the received data and offers less power consumption and memory utilization of the sensor node.
