Traffic Information Systems (TIS) are one of the key non-safety application areas of Vehicular Ad Hoc Networks (VANETs). As such, TIS are much less delay sensitive compared to safety applications, which have recently attracted a lot of attention in VANET research. We propose a new message dissemination protocol, Adaptive Traffic Beacon (ATB), which is fully distributed and uses adaptive beaconing based on two key metrics: 1) the message utility; and 2) the channel quality. It is shown that adaptive beaconing leads to a much broader dissemination of messages (in terms of penetration rate) than flooding-based approaches, albeit at a slower rate. Adaptive beaconing thus seems to be much more suitable for TIS than flooding-based protocols.
