| Abstract: | Aimed at the network disconnecting issue in VANET, on the basis of existing carry-forward mechanism, a new broadcasting protocol based on the use of fixed facility RSU was proposed to shorten the re-healing time between nodes. A detailed analysis was made about the delivery process of messages and the calculation method of re-healing time in two kinds of cases, and a comparison with SCB and SCF mechanisms through simulation experiments was conducted. The results showed that the new broadcasting protocol based on RSU can greatly reduce the re-healing time in the case of network dis- connection. |
