Abstract In vehicular networks, safety-related applications usually operate based on wireless broadcast since warning messages (e.g., accident, blocked street, traffic congestion, etc.) need to be delivered to all nearby vehicles. Sometimes vehicles that have detected emergency events only need to broadcast the emergency messages to nearby vehicles within the transmission coverage, and a single-hop packet broadcast may be acceptable for this type of applications. In such a case, the MAC protocol will become the dominant component that determines the transmission efficiency of an emergency message.
