ANALYSIS OF SECURITY ATTACKS FOR AODV PROTOCOL IN MANET

There are various challenges that are faced in the Ad-hoc environment. These are mostly due to the resource poorness of these networks. They are usually set up in situations of emergency, for temporary operations or simply if there are no resources to set up elaborate networks. The solutions for conventional networks are usually not sufficient to provide efficient Ad-hoc operations. The wireless nature of communication and lack of any security infrastructure raise several security problems. In this paper we attempt to analyze various kinds of security threats that may be imposed on an ad hoc network. We also discussed the nature and the serious ness of the various attacks on the popular protocols like AODV and DSR. 1
