Abstract
A device may receive a message identifying an incident associated with a vehicle and may forgo rebroadcast of the message when the message was previously received. The device may store the message when the message was not previously received and may calculate a distance from the device to the vehicle based on a received power associated with the message. The device may determine whether to stop rebroadcasting the message based on a stop condition and based on the distance or a current location of the device and may calculate a particular coverage area of a rebroadcasted message based on coverage areas of the device and the vehicle. The device may determine, based on not determining to stop rebroadcasting the message and based on the distance or the particular coverage area, a delay time to wait before rebroadcasting the message and may rebroadcast the message after the delay time expires.
