Alert propagation in mobile ad hoc networks

Intrusion/misbehavior detection and response are two important components for defending against various attacks in mobile ad hoc networks. Unfortunately, there is a gap between local intrusion/misbehavior detection and network-wide response in such networks. To bridge this gap, alert propagation, aiming to spread alert messages to the whole network upon detection of malicious/abnormal activity, is a viable solution but has been overlooked.
