Abstract 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 timerbased 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.

1 Introduction Vehicular ad-hoc networks (VANETs) have always attracted positive attention since the concept was first proposed. Its applications include driving safety, traffic control, entertainment, and the like. Inter-vehicle communication (IVC) is a key technique for realizing these applications. In contrast to static ad-hoc networks, the most important special property in VANETs is high-speed mobility, which renders wireless connections between two vehicles intermittent. Therefore, many organizations and researchers have proposed solutions to this problem (e.g. IEEE 802.11p). However, some kinds of information do not rely on continuous connection to transmission. An important fact is that numerous vehicles ‘desire’ to have such vehicular information as safety-related data and leisure information. This classification of data is to be recognized as the knowledge-based leisure information for sharing value-added information regarding individual through entertainment, travel, music, sports, games, video, social networking, chatting, and healthy living. The strategies for meeting this requirement deal with information dissemination. A simple way to realize these objectives depends on broadcast, which is widely used in various dissemination protocols. The simplest application of broadcast is called floodin
