An Efficient Cluster-Based Approach to Thwart Wormhole Attack in Adhoc Networks

Abstract

Mobile Ad-hoc networks is an ascertaining domain with promising advancements, attracting researchers with a scope of enhancements and evolutions. These networks lack a definite structure and are autonomous with dynamic nature. The strength of the Ad-hoc network lies in the routing protocols making it an apt choice for transmission. With several types of routing protocols available our focus is on LGF (Location-based Geo-casting and Forwarding) protocol that falls in Position based category. LGF assures to grab the attention with its feature of low bandwidth consumption and routing overhead at the cost of unvolunteered attacks resulting in compromising the security of data. In our approach, we present a technique to overcome the profound attacks like Wormhole and Blackhole by aggregating LGF with k++ Means Clustering aiming at route optimization and promoting security services. The proposed mechanism is evaluated against QoS factors like End to End delay, Delivery Ratio, Load balancing of LGF using Simulator NS3.2 which envisioned drastic performance acceleration in the aforementioned model.

Hybrid state analysis with improved firefly optimized linear congestion models of WSNs for DDOS & CRA attacks

“…The mitigation classification technique utilizes an aspect of reduced/stop packet transfer. An attack in the middle of the way that interrupts the flow of packets is one of the DOS attacks which slows down the data flow and can defend by grouping into various clusters ( Abdul Basith & Shankar, 2020a ; Abdul Basith & Shankar, 2020b ; Spurthy & Shankar, 2020 ). With network participation of all the nodes for data, transmission needs a large amount of power that can resolve by node optimization.…”

Multi-Step Detection of Simplex and Duplex Wormhole Attacks over Wireless Sensor Networks

“…Wormhole attacks, which have significant impacts on the network layer, are one of the biggest dangers. Wormhole attacks, according to research, can disrupt network routing, location-based wireless security, and data aggregation [3][4][5][6]. A wormhole attack can be launched by a single node or by a pair of cooperating nodes [7].…”
