A SECURE INTRUSION DETECTION SYSTEM FOR MANETS USING EAACK

Abstract

The migration to wireless network from wired network has been a global trend since the evolution of wireless network. Among all the types of wireless networks, MANET (Mobile Ad hoc NETwork) is one of the most unique and distinctive application. Unlike traditional wireless networks, MANET doesn't require a fixed infrastructure. Every single node in MANET acts as both transmitter and receiver. Nodes communicate with each other directly if they are within a communication range, otherwise they rely on their neighbor nodes to transmit messages. MANET is capable of creating a self-configuring and self-maintaining network without the need of a centralized infrastructure and this ability made it famous in mission critical use such as military or emergency. However MANETs are vulnerable malicious attacks because of open medium and its wide distribution of nodes, hence, it is crucial to develop efficient intrusion detection systems for MANET to protect it from attacks. Our proposed system named EAACK (Enhanced Adaptive ACKnowledgment) is specially designed for MANET.As compared to alternative approaches; EAACK demonstrates higher intrusion detection rates and also does not greatly affect the network performance
