SD-AODV: A Protocol for Secure and Dynamic Data Dissemination in Mobile Ad Hoc Network

TL;DR

This paper introduces SD-AODV, a secure and dynamic routing protocol for mobile ad hoc networks that effectively defends against wormhole, Byzantine, and blackhole attacks, maintaining network performance under malicious conditions.

Contribution

The paper proposes SD-AODV, an extension of AODV, which enhances security against specific routing attacks in mobile ad hoc networks.

Findings

Network performance remains stable under attack conditions.

SD-AODV effectively defends against wormhole, Byzantine, and blackhole attacks.

Simulation results show no degradation in key performance metrics.

Abstract

Security remains as a major concern in the mobile ad hoc networks. This paper presents a new protocol SD-AODV, which is an extension of the exiting protocol AODV. The proposed protocol is made secure and dynamic against three main types of routing attacks- wormhole attack, byzantine attack and blackhole attack. SD-AODV protocol was evaluated through simulation experiments done on Glomosim and performance of the network was measured in terms of packet delivery fraction, average end-to-end delay, global throughput and route errors of a mobile ad hoc network where a defined percentage of nodes behave maliciously. Experimentally it was found that the performance of the network did not degrade in the presence of the above said attacks indicating that the proposed protocol was secure against these attacks.
