A Secure & Hybrid Authentication Protocol of Intrusion Detection System for MANET

-In MANET, security is the toughest and very challenging area, because nodes are without any
predefined framework. This is due to the high mobility of outstanding vulnerabilities and attacks of the
malicious nodes in the intrusion detection system of Mobile Ad Hoc Networks (MANET). A secure & hybrid
protocol design has been proposed, in order to improve the detection efficiency and also to improvise the
performance of Intrusion Detection Systems for MANET. Based on the hybrid techniques with the aid of key
management authentication and combining with a fuzzy based decision model for detecting the misbehaving
attacks. Identifying group of physical attacker and finding its probabilities and its side effects are evaluated. To
discover the misbehaving attackers and predicting it effects by using Fuzzy based model. In the proposed hybrid
authentication protocol for malicious node detection system and for avoiding problems related to missing
packet, delay in the nodes and false misbehavior reports. Secure hybrid authentication protocol is used to detect
various attacks in MANETs by incorporating hybrid techniques such as fuzzy schemes and key organization
method. Hence the different ratio of all the parameter were experimented and analyzed, in terms of the attack
prediction rate, attack precision, packet drop ratio and end to end delivery ratio. The schemes were compared
with the existing mechanisms and results show that proposed hybrid authentication has superior improvement in
the performance
