Abstract

In this paper, a new Honest-rate base collaborative Intrusion Detection System (HIDS) has been proposed for mobile, ad-hoc networks. The method uses promiscuous mode of working along with rating and collaborative decision making based on multiple threshold values. All nodes join the network with an initial value of 1 for an honesty rate index, termed as h-rate. The h-rate of a node dynamically increases or decreases depending on its behavior. A node is rewarded when it forwards packets for other nodes. It is penalized when it does some malicious act like dropping packets, etc. The h-rate for a node NX is recomputed based on its current h-rate, and the rewards or penalty points that it has accrued. The proposed rule-based scheme reduces the h-rate of a node gradually, if it behaves abnormally. This provides an inherent mechanism against phantom intrusion detection. The h-rate may also be used for secure routing in MANET.
