Abstract

This study introduces a brand-new security technique for MANETs to use with the AODV (Adhoc On-demand Distance Vector) routing protocol in order to improve its security and performance when under attack like explicit packet dropping (EPDA) and implicit packet dropping (IPDA). The first version of the AODV routing protocol did not include any safeguards. As a result, it can't stop any cyberattacks of any kind. However, AODV is safe due to the availability of numerous security methods. The technology that identifies them also provides a network-based strategy for minimizing the number of attackers. More investigation into this field, however, revealed a critical vulnerability in all currently available safe routing systems. Thus, existing security measures are resource-heavy and call for a sophisticated key-management infrastructure. In this paper, we describe a new way to protect the AODV routing protocol that combines digital signature and hash chain. This method can protect itself from hostile and unauthenticated nodes with little effect on performance.
