Prevention and Detection of Wormhole Attack in Mobile Adhoc Network Using Clustering and RTT

Abstract

A security constraint in mobile adhoc network is very critical task. Some critical security issue such as black hole attack, wormhole attack, sinkhole attack, prevention and detection of attack is major challenge. For the detection of wormhole attack various authors used various technique such as clock synchronization, threshold based technique, nearest neighbor node selection method. In this dissertation modified the IMAODV protocol in terms of IMAODV protocol.In this paper modified the AODV routing protocol for the detection of wormhole attack. The modified protocol is called secured energy efficient routing protocol (IMAODV). The IMAODV protocol based on two functions one is threshold based function and one is energy based function. The threshold based function measure the distance of normal node and wormhole node. Our proposed algorithm is
