Abstract
Wireless Sensor Network (WSN) is the most promising inventions that can find its application in diverse fields such as army surveillance and forest fire detection. Multi-hop routing is followed in WSN, and the greatest security with effect to identity deception is produced through replaying routing information. An inevitable role is played by trust in the sensor network in case of military and other applications. Serious research work is being conducted on secured data aggregation. Longestablished cryptographic trust-aware routing protocols which are being used currently have become outdated, and their proficiency in tackling the situation is not much satisfactory. This ultimately results in increased complexity, poor link quality and high overhead when it comes to a number of cryptographic methods. This work deals with fuzzy logic based trust evaluation technique that can acquire secured routing. Direct Random Propagation (DRP) protocol and fuzzy logic are used in calculating the trust of the nodes. Flooding attack and black hole are proposed, and it eliminates the attack. The threshold value is compared with trust value. The ultimate result shows that the method that is proposed provides lesser interception probability, packet loss and end-to-end delay.
