Abstract: This paper introduces the structure of intrusion detection system in mobile Ad Hoc networks, and analyzes a model of layered weighted IDS and clustering algorithm. According to the hierarchical structure, it gives a scheme of broadcasting and transferring alert message using digital signature. It designs the packet format of alert message, and gives the source code of ELFhash Hashing function.

Key words: mobile Ad Hoc networks(MANET), intrusion detection system(IDS), layered weighted clustering, Hashing function
