SRDAODV: A Hybrid Secure Routing Protocol for Mobile Ad-Hoc Networks

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