Abstract

A system and method for communicating vehicle management information between vehicles using an ad-hoc network. The system and method forms a routing path based on vehicle management information of individual vehicles, and communicates the vehicle management information between the vehicles along the routing path. A source vehicle collects its own vehicle driving information, and creates vehicle management information of the source vehicle based on the vehicle driving information. The source vehicle sets up a routing condition composed of predetermined vehicle traveling requirements based on the vehicle management information, and transmits a vehicle management information message having the routing condition and the vehicle management information to nearby vehicles. The nearby vehicles search for the routing condition upon receiving the vehicle management information message, and determine whether to route the vehicle management information message according to the routing condition.
