ABGF-AODV protocol to prevent black-hole, gray-hole and flooding attacks in MANET

Wireless ad hoc networks play a pivotal role in wireless communication systems. MANETs find extensive applications across various domains, encompassing real-time information exchange, network partitioning, rescue operations, interpersonal communication, and data sharing. MANET works as dynamic wireless networks without a fixed infrastructure in which nodes freely join or leave the network at any time. The absence of fixed infrastructure coupled with openness characteristics of MANET poses significant security issues. This paper proposes a technique called as Anti-blackhole, Gray-hole, and Flooding attack-Ad-hoc On-Demand Distance Vector (ABGF-AODV) to identify and thwart the impact of attacks in MANETs. Through extensive evaluation utilizing the NS-2 simulator, the performance of the proposed protocol is thoroughly examined. The results showcase the robustness of the ABGF-AODV protocol against various attacks, yielding better performance as compared with existing state of art technique.
