A MODIFIED ADAPTIVE-SAODV PROTOTYPE FOR PERFORMANCE ENHANCEMENT IN MANET

Abstract

Mobile ad hoc networks are vulnerable to various security threats because of its dynamic topology and selfconfigurable nature. SAODV (secured Ad hoc On Demand Vector routing) is one of the popular existing secured mechanism which takes help of digital signature and hash chain techniques to secured AODV packets. Since, digital signature technique consumes heavy computational time, the degradation of SAODV performance can be a major issue. In a recent work called A-SAODV( Adaptive SAODV), an adaptive mechanism that tunes the behaviour of SAODV t improve its performance. In this paper we have proposed an extension to Adaptive- SAODV of the secure AODV protocol extension, which includes further filtering strategies aimed at improving its performance. Moreover, we analyze how our proposed algorithm can help to further improve the performance of adaptive SAODV.
