Abstract:

The mobile Ad Hoe network（MANETS） are vulnerable to attacks for the unique characteristics of MANETs, such as open network architecture, shared wire less medium, highly dynamic network topology, and stringent resource constraints. In MANETs, each node acting as a rooter to scarch and maintain the roo l to the other nodes. Rool security is an especially important part in MANETs security, in this paper, we design an IDS model （called IDS_trust） based on the trusl spectrum by the trust mechanism in decision-and-support systems,and present a new security solution.

Key words: ad hoc network, root security;trust spectrum, IDS_trust
