VANET VANET Warning Message Propagation Method for Electric Wave Blind Area

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a VANET warning message delivery method in a radio-shadowed area, and more particularly, to a VANET warning message delivery technique that uses a routing information to dualize a node state into a direct mode and a redirect mode.A method of transmitting a VANET warning message in a radio-shaded area according to the present invention includes: receiving an initial warning message from an emergency-occurring node; Confirming whether the intersection weight is 1 and checking whether the node is in an intersection area; Proceeding to a redirect mode if the intersection weight is not equal to 1; Confirming whether there is only one node when the intersection weight is 1; Forwarding a warning message if there is only one node; If there is only one node, confirming that it is a high delivery priority; A step of delivering a warning message if it is confirmed as a high delivery order, and a step of waiting if the delivery order does not have a high delivery order.;
