In this work, we present a new mobility model, that can be used in a mobile communication system. The differential of the present model are that it depends on the state, oi the model takes in consideration the congestion phenomenon, the speed falls when the number of users of the system increases. Before presenting the new model, we will make a description of the mobile communication system and the mobility models in the literatm-e. After that, we present the state-dependent mobility model applied the traffic of pedestrians and vehicles, that can be applied in communication system. We also present, a description of the implemented simulation model, and the occured changes so that it could be applied to the system of mobile communication. A great number of experiments has been carried through to prove the effectiveness of our model, being demonstrated that the new approach is promissing. Finally, we will show other problems that can be studied based on the propused model.
