A Nobel Defence Scheme Against Selfish Node Attack in MANET

TL;DR

This paper proposes a novel intrusion detection system for MANETs that effectively identifies and blocks selfish nodes, significantly improving network performance and eliminating infection from such attacks.

Contribution

A new IDS algorithm specifically designed to detect and prevent selfish node attacks in MANETs, enhancing security without compromising network performance.

Findings

Network performance improved up to 92% after IDS deployment.

0% infection rate achieved against selfish node attacks.

Effective detection and blocking of selfish nodes in MANETs.

Abstract

Security is one of the major issue in wired and wireless network but due to the presence of centralized administration not difficult to find out misbehavior in network other than in Mobile Ad hoc Network due to the absence of centralized management and frequently changes in topology security is one of a major issue in MANET. Only prevention methods for attack are not enough. In this paper a new Intrusion Detection System (IDS) algorithm has proposed against selfish node attack to secure MANET. Here the behavior of selfish node is unnecessary flooding the information in network and block all types of packets transferring between the reliable nodes. Proposed IDS Algorithm identifies the behavior of selfish node and also blocked their misbehavior activities. In case of selfish node attack network performance is almost negligible but after applying IDS on attack network performance is enhanced up to 92% and provides 0% Infection rate from attack.
