New Secure Intrusion-Detection System for Manet’s Using Hybrid Cryptography Techniques

Abstract-The technology change in wireless from wired has been a comprehensive trend in the past few years. The mobility and scalability brought by wireless network prepared it possible in many applications. Among all the contemporary wireless networks, Mobile Ad hoc NETworks (MANET) is one of the most vital and exclusive applications. On the contrary to traditional network architecture, MANET does not need a stable network infrastructure; the self-configuring ability of nodes in MANET made it popular among critical mission application like military use or emergency retrieval. However, the open medium and wide sharing of node make MANET vulnerable to malicious attackers. Hear crucial to develop capable intrusion-detection mechanisms to guard MANET from attacks. With the enhancements of the technology and changed in hardware costs, we are watching a current trend of expanding MANETs into industrial applications. To propose and implement a new intrusion-detection specially designed for MANETs. Compared to contemporary approaches, new intrusion-detection system demonstrates higher malicious-behaviour-detection rates in certain conditions while does not greatly affect the network performances
