TRUST BASED MULTI PATH ROUTING & TOPOLOGY HIDING IN MOBILE AD HOC NETWORK : A SECURE PERSPECTIVE

Abstract

Mobile Ad-hoc Network (MANET) has been atracted large number of researchers in recent years due to its inherent potential for the data transmission .The peculiar charectristics of MANET like limited battery power, mobility of nodes , limited bandwidth provides challenge for the effective and efficient routing among the mobile nodes and at the same time it is necessary to ensure secure data transmission within the given constraints of MANET . Multipath routing is much more flexible and effective approach of routing . Topology hiding protocol i.e. TOHIP resolves the topology exposure problem im multi path routing . FL-TOHIP & AFL-TOHIP has demostrated the improvement in solution searching and enhanced the efficiency of TOHIP . Malicious nodes and other attacks make MANET vulnerable even with topology hiding . Trust based aapproach is used to secure communication using the trust between the neighbours . Trust based approach is an alternative to cryptographic tecniques . This paper evaluates variois trust based protocols and provide a direction to integrate trust based approach with topology hiding multi path routing protocols in MANET to provide optimal data transmission with utmost security .
