Message are broadcast in a vehicular environment using a network of nodes, wherein each node includes a transceiver and a processor arranged in a vehicle, and a bandwidth of the network is partitioned into a control channel (CCH) and multiple service channel (SCH). Time is partitioned into alternating control channel intervals (CCHI) and service channel intervals (SCHI). A source node detects an event and broadcasts a message related to the event. The message specifies current channels and next channels used by the source node to broadcast the message. The message is received in a set of relay nodes. Then, each relay node that receives the message rebroadcasts the message during the SCHI on the CCH or any other channels not specified in the message.
