Survey on EAACK - A Secure Intrusion-Detection System for MANETs

Abstract

The past few decade migration to wireless network from wired network has been a global trend. Wireless network made it possible in many applications to have mobility and scalability. Among all the modern wireless networks, Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications. MANET is more popular now days. On the conflicting to traditional network architecture, MANET not has a fixed network infrastructure; every single node works as both a transmitter and a receiver. Nodes within same communication range are communicated directly with each other. Otherwise, they depend on their neighbors to relay messages. Because of the self-configuring ability of nodes in MANET made it popular among critical mission applications like military use or emergency recovery. Now days, security has become a very important service in Mobile Adhoc Network. As Compared with other networks, MANETs are more vulnerable to various types of attacks. This paper presents an overview of Secure Intrusion-Detection Systems for discovering malicious nodes and attacks on MANETs. Because of some special characteristics of MANETs, prevention mechanisms alone are not satisfied to manage the secure networks. In this, detection should be focused as another part before an attacker can damage the structure of the system. This paper gives an overall overview of IDS architecture for improving the security level of MANETs. For enhancing the security based on security attributes and then various algorithms like RSA and DSA.
