Abstract

A Wireless ad-hoc network is a temporary network set up by wireless mobile computers (or nodes) moving arbitrary in the places that have no network infrastructure called as Mobile Ad-hoc Network (MANET). As MANET does not have fixed infrastructure and central administration, due to security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of nodes. Wormhole attack is one of the severe attacks which absorb all data packet instead of sending it to destination. An Enhanced HSAM technique is used in order to compare the different performance parameters with HSAM and the results are monitored with the use of network simulator.
