Message management protocol persistent geocast routing |
摘要 |
A system and method for providing a protocol to maintain a persistent warning message in a region of interest. The protocol begins its operation when a hazardous condition is detected by a vehicle. The detecting vehicle uses a multi-hop geocast broadcasting process to transmit a warning message to other vehicles in the region of interest. When the vehicles in the region of interest receive the warning message, they are prevented from re-broadcasting the message for a first predetermined period of time. After the first predetermined period of time has expired, a contentious timing process is used to determine which of those vehicles will re-broadcast the message to other vehicles entering the region of interest. This process of re-broadcasting continues until a second predetermined period of time expires at which time the message is not re-broadcast. |
