A Survey on IDS and A Mechanism for Detecting Malicious Nodes Using Enhanced Secure Acknowledgment (ES-ACK)

Abstract

Wireless communication represents a major industrial stake in the coming years. The ability to be moved from one place to another and to make larger brought by wireless network made it possible in many applications. It targets applications in harsh environments such as war zones, emergency recovery, power plants and warships etc. MANETs is one among the wireless technology which is widely used. MANETs does not need any preconfigurations or permanent network architecture or infrastructure compared to wired technology. The wireless links between the nodes together with the active or changing nature of ad hoc network, increases the challenges of design and implement intrusion detection during the attacks. The intrusion detection system is achieved through a mechanism called Enhanced Secure Acknowledgment (ES-ACK) which is more elegant than watchdog. Another challenging issue in MANETs is the data integrity, which is achieved through Message Authentication Code (MAC).
