Geo-Social Mobility Model for VANET Simulation

Vehicular Ad Hoc Network (VANET) can be viewed as a special case of an ad hoc network formed by moving vehicles communicating through short-to-medium range wireless transmission. This emerging wireless technology allowed for a wide range of applications varying from safety and accident avoidance to leisure and entertainment. The VANET's special features, such as high node mobility, made the design and validation of its protocols a challenging task. A realistic simulation environment is then required. Since the vehicles mobility is driven by the human mobility characteristics and is controlled by the geographical restrictions of the roads, the work presented in this paper is aimed to having a realistic mobility model that incorporates both the social aspects of human mobility together with the geographical restrictions that governs the movement of the mobile nodes. The model is based on using realistic data sets rather than randomly generated data.
