The choice of a mobility model has a significant impact on the performance of mobile network simulations. In order to accurately evaluate performance it is important to mimic the environment in which the mobile network will be deployed. Thus, using real mobility models for simulation environments are preferred to synthetic models. Historically however, unrealistic movement models have been mostly used, due to their simplicity and mathematical tractability. Recently, some mobility models have been derived from real user traces; however, they have not yet been adopted by the mobile research community for evaluation of protocol performance. The contribution of this poster is to announce that we have implemented a generalized real mobility model generator (RealMobGen) for use with the NS-2 network simulator.
