Vehicle-to-vehicle communication and probabilistic broadcast are important means for information dissemination in vehicular ad-hoc networks (VANETs). In contrast to static ad-hoc networks, high-speed mobility makes wireless connection between two vehicles intermittent. Nevertheless, some kinds of information do not rely on continuous connection for transmission. An important fact is that numerous vehicles ‘desire’ to have such information as safety-related data and leisure information. In recent years, an excessive number of protocols have attached themselves to critical information dissemination, and the existing protocols already have excellent performance. People severely neglect leisure information because of its low importance. Even so, the dissemination of leisure information is an important issue in VANET when, for example, people take long trips on highways. Therefore, we propose interest-aware probabilistic dissemination (IAPD) of leisure information in VANET, which combines probabilistic broadcast and timer-based broadcast techniques. We also develop a state transition system for leisure-information dissemination. The simulation results show that IAPD cost less than restriction flooding and simple schemes in obtaining a high reception rate.
