Novel Filtering-Based Approach Using Fuzzy Logic for Prevention of Adversaries in Sensory Application

Security problems associated with the Wireless Sensor Network (WSN) have yet not met it fail-proof solution against the most lethal threat. After reviewing existing security solution, it was felt that there is a wide scope of improvement as existing system still cannot offer certainty in its decision of adversaries, whether it is identification or prevention of any threat. Therefore, the proposed system introduces a novel mechanism where fuzzy logic has been applied to filter down the decisions on the basis of unique pattern of energy and distance factors to identify and prevent the adversary from stealing the public keys within the sensor node. The study outcome shows that proposed system offers significant security without affecting the communication performance. In fact, proposed system exhibits good residual energy and sustaining data delivery performance for a longer iteration. © Springer Nature Switzerland AG 2019.
