TL;DR
This paper proposes a distributed security scheme for MANETs that detects and prevents specific DoS and DDoS attacks targeting routing protocols, improving network resilience without extra overhead.
Contribution
A novel proactive, distributed security scheme for MANETs that detects and mitigates specific DoS and DDoS attacks on AODV routing protocol.
Findings
Better attack detection and prevention compared to existing methods
No additional overhead introduced by the scheme
Effective against both DoS and DDoS attacks
Abstract
In Mobile Ad Hoc Networks (MANET), various types of Denial of Service Attacks (DoS) are possible because of the inherent limitations of its routing protocols. Considering the Ad Hoc On Demand Vector (AODV) routing protocol as the base protocol it is possible to find a suitable solution to over-come the attack of initiating / forwarding fake Route Requests (RREQs) that lead to hogging of network resources and hence denial of service to genuine nodes. In this paper, a proactive scheme is proposed that could prevent a specific kind of DoS attack and identify the misbehaving node. Since the proposed scheme is distributed in nature it has the capability to prevent Distributed DoS (DDoS) as well. The performance of the proposed algorithm in a series of simulations reveal that the proposed scheme provides a better solution than existing approaches with no extra overhead.
