Enhancing Mobile Ad Hoc Network Security: An Anomaly Detection Approach Using Support Vector Machine for Black-Hole Attack Detection

초록

In the contemporary environment, mobile ad hoc networks (MANETs) have become necessary. They are absolutely vital in a variety of situations, where setting up a network quickly is required; however, this is infeasible due to low resources. Ad hoc networks have many applications: education, on the front lines of battle, rescue missions, etc. These networks are distinguished by high mobility and constrained computing, storage, and energy capabilities. The main aim of this research is to create a method for identifying blackhole attacks through anomaly detection techniques utilizing Support Vector Machines (SVM). Our detection system looks at node activity to scan network traffic for irregularities. In blackhole scenarios, the attackers exhibit distinct behavioral characteristics that distinguish them from other nodes. This can be efficiently detected by the proposed SVM-based detection system. The proposed detection system is designed to analyze network traffic and identify anomalies by examining node behaviors. Specifically, in the context of blackhole threats, it distinguishes the attackers from normal nodes based on behavioral characteristics. Using this approach, the system effectively detects blackhole attacks. The results demonstrate a very high level of accuracy in detecting blackhole attacks, confirming its efficacy in ensuring the security of mobile ad hoc networks (MANETs) by identifying and isolating malicious nodes. This solution is particularly valuable in scenarios like military operations and disaster management where a reliable communication system is crucial. Furthermore, the proposed detection method, ADS-SVM, was compared to two other methods (J48 classifier and NB classifier) from different researchers. The results indicate that ADS-SVM outperforms the other methods with a detection accuracy of 99.96%, surpassing the 99.2% achieved by J48 classifier and the 96.5% achieved by NB classifier. The results indicate that ADS-SVM is a highly efficient approach for identifying blackhole attacks in MANETs, potentially offering superior accuracy compared to other related methods.
