UrbiSim: A framework for simulation of ad hoc networks in realistic urban environment

In this paper, we present UrbiSim, a new simulation framework for delay tolerant and ad hoc network research applied to urban environments. By providing two levels of mobility modeling, this work tries to cope with two of the current limitations of simulation models: realistically mimicking mobility at an individual level and offering a global movement pattern, reflecting the social behavior of users. Conceived as a framework, independent of any simulation tool, UrbiSim is made to incorporate real-world data and extended to cover many simulation use-cases including pedestrian and vehicular mobility. As the user behavior model might be based on membership of several social groups, it is also a powerful tool to investigate the impact of social interactions on ad hoc networks.
