A Trust-Based IDS for the AODV Protocol

摘要

Routing in ad hoc networks is based on mutual trust between collaborating nodes. Security problems arise when supposedly honest nodes lie deliberately to maximize their profit. In this article, we are interested in detecting misbehaving nodes within the ad hoc routing protocol AODV. We propose and implement a real-time intrusion detection system based on implicit trust relations: a node implementing this system collects its neighbors' routing messages and reasons on them to decide on their honesty. We also evaluate our implementation, and, based on simulations, show that the system we have developed to detect dishonest behavior is efficient.
