Abstract
In a vehicle communication network, some vehicles may be used by attackers to send false information to other vehicles which may jeopardize the safety of other vehicles. Vehicles should be able to detect malicious communications activities and to mitigate the impact of malicious vehicles by evicting (eliminating) suspected malicious vehicles from the system. Evicting a vehicle is to ignore the messages sent from the vehicle for a specified time period. Voting and sacrifice principles are combined using a mathematical model based on the “Mafia Game”. The Mafia Game model focuses on the relative size of the group of attackers within a neighborhood necessary to dominate the entire network in the neighborhood (i.e., to eventually evict all the innocent vehicles).
