Trust-Based Security Technique to Curb Cooperative Blackhole Attacks in Mobile Ad Hoc Networks using OTB-DSR Protocol in NS-3

Abstract

The advent of mobile technology led to the emergence of Mobile Ad-hoc networks (MANETs). These networks have no infrastructure and central authority. Nodes in MANETs act as both routers and hosts. MANET nodes join and leave the network at will making the network topology dynamic. MANETs are prone to both passive and active security attacks. Blackhole is a denial of service attack under active attacks. Blackhole nodes work in collaboration forming cooperative black hole attacks. The attacks drop or redirecting data packets on transit. Cooperative blackhole attacks are dangerous in operations where communication is critical. This paper proposes a Trust-Based Resilient Cooperative Bait Detection Technique (TB-RCBDT), an integration of the Resilient Cooperative Bait Detection Technique (RCBDT) and Optimized Trust-Based Dynamic Source Routing (OTB-DSR).
