Roadway communication system with multicast

An apparatus for cooperative communication via multicast communications comprising:

• a memory;
• and
• processing circuitry coupled to the memory, wherein the processing circuitry is configured to:
• generate a multicast group address based, at least in part, on a geographical region of the apparatus;
• broadcast the multicast group address to allow cooperative communication enabled devices to join a multicast group corresponding to the multicast group address;
• receive requests from the cooperative communication enabled devices to join the multicast group;
• and
• transmit cooperative communication messages to the multicast group via multicast communications.

A tangible, non-transitory, computer-readable medium comprising instructions that, when executed by a processor, direct the processor to create a multicast group for cooperative communications, the instructions to direct the processor to:

• generate a multicast group address based, at least in part, on a geographical region;
• control a wireless transmission to broadcast the multicast group address to allow cooperative communication enabled devices to join a multicast group corresponding to the multicast group address;
• receive requests from the cooperative communication enabled devices to join the multicast group;
• and
• control a wireless transmission of cooperative communication messages to the multicast group via multicast communications.

A method of providing cooperative communication messages via multicast, comprising

• generating a multicast group address based, at least in part, on a geographical region of a multicast group;
• broadcasting the multicast group address to allow cooperative communication enabled devices to join the multicast group;
• receiving requests from the cooperative communication enabled devices to join the multicast group;
• and
• transmitting cooperative communication messages to the multicast group via multicast communications.
