An apparatus comprising a processor and a transceiver. The processor may (i) receive messages from a plurality of vehicles and (ii) determine relative coordinates of the vehicles based on the messages. The transceiver may (i) communicate the messages using a first channel in a first range and (ii) communicate short messages using a second channel in a second range. Communicating using the second channel may consume more power than communicating using the first channel. The messages may be sent from the transceiver to a cluster head within the first range. The short messages may communicate less data than the messages. The short messages may be sent directly to a target vehicle outside of the first range to determine an associated cluster head for the target vehicle. The messages may be sent to the target vehicle from the associated cluster head via the cluster head within the first range.
