Abstract:

To reduce various intrusion behaviors   that might damage  the drivers and passengers in vehicular ad-hoc networks (VANETs), a mixed intrusion detection scheme (MIDS) based on different traffic scenarios was proposed. While the vehicles were running on the same road, message integrity method (MIM) was used, otherwise VOTE method was chosen. When the network condition was allowed, the corresponding scenario information could be requested to prove the reality of alert messages. The simulation results showed that the proposed method outperformed the existing intrusion detection methods in terms of communication delay and detection rate. Meanwhile, this method could overcome the limitations of existing schemes and could detect many intrusion behaviors efficiently.

Key words: vehicular ad-hoc networks, intrusion behaviors, mixed intrusion detection scheme, intrusion detection
