Abstract

Objectives: To counteract grey hole and black hole attacks, the proposed method deploys a hybrid framework along with the Ad hoc on-demand distance vector (AODV) routing protocol. A modified protocol is called as SRDAODV (Secure Route Discovery-Adhoc On-Demand Distance Vector). Methods: The proposed work establishes secure route from secure node discovery, which protects from sequential attacks. The proposed framework has three significant components Node Authentication, Secure Neighbor discovery and route establishment, and Node Isolation system. Findings: Performance metrics like packet delivery ratio and delay are used to assess this protocol’s effectiveness. The SRD-AODV protocol contrasts with other active protocols as well as AODV. SRD-AODV has a PDR that is greater by 4.92% than EDRIAODV and 12.23% than AODV because it excludes network attacks, has flawless routes, and prevents packets drop or connections fail. This is because SRD-AODV has more perfect routes. The proposed SRD-AODV algorithm achieves 58.5% less E2E delay than AODV and 44.5% less than EDRI-AODV. Novelty: This protocol uses a variety of elements and techniques to establish efficient authentication using Elliptic Curve Diffie-Hellman algorithm (ECDHA) techniques, offering both proactive and reactive solutions. Additionally, this tries to secure the data packets and routing table information. Finally, it also aims to identify and stop incursions from sequential attacks in MANET.
