Systems and methods for utilizing geofence areas and multicasting to share basic safety message data with vehicles

A device, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, configured to:
• generate a difference geofence area based on determining a difference between a primary geofence area and a secondary geofence area,
• wherein the primary geofence area includes a first set of vehicles within boundaries of the primary geofence area,
• wherein the secondary geofence area is greater in size than the primary geofence area, and
• wherein the difference geofence area includes a second set of vehicles that is different than the first set of vehicles, within boundaries of the difference geofence area;
• generate a message based on basic safety message (BSM) data associated with the second set of vehicles;
• and
• multicast the message to the first set of vehicles.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the device to:
• generate a difference geofence area based on determining a difference between a primary geofence area and a secondary geofence area,
• wherein the primary geofence area includes a first set of vehicles within boundaries of the primary geofence area,
• wherein the secondary geofence area is greater in size than the primary geofence area, and
• wherein the difference geofence area includes a second set of vehicles that is different than the first set of vehicles, within boundaries of the difference geofence area;
• generate, based on basic safety message (BSM) data associated with the second set of vehicles, a message;
• and
• multicast the message to the first set of vehicles.
