Distributed Secure Intrusion - Detection System for Wireless Sensor Network

Invention of wireless network has brought up drastic change in networking. Mobile Ad hoc NETwork (MANET) has been evolved as one of the promising technology based on implementation of wireless network. Providing mobility, flexible infrastructure, fast and low cost deplyoment are the key features of MANET. MANET is being most widely used wireless technology has limited security against network attacks. Dynamic configurability adds flexibility to MANET but it makes it vulnerable to attacks like DoS, Wormhole, Man-In-Middle Attack, IP Spoofing Attacks. In this paper, we propose an intrusion detection system Extended Enhanced Adaptive ACKnowledgement (E-EAACK) which will detect the intrusion and localize the attacker. This system includes security components of prevention, detection and reaction. Specially designed for MANET, E-EAACK serves in detection of malicious behaviour without much affecting Network Performance. In addition it will detect and localize multiple IP Spoofing Attacks. We propose, the use of digital signature for authentication of nodes and S-ACK scheme for detecting anomalous behaviour in network. The implementation of GADE model for detection of attacks and IDOL framework for localization of the intruder makes E-EAACK a more effective security solution for MANET.
