The wide diffusion of smart portable devices allows the collection of a big amount of data concerning the activities of users from mobile apps. We focus our attention on location data, i.e. mobility traces, of a set of users in a crowd. Data collected from these mobile systems are studied following two axies: - Mobility models are used to simulate the behavior of users to develop opportunistic forwarding algorithms. We compare real and synthetic mobility traces to show the distance between the reality and the models. - Information on mobility may endanger the privacy of users. We analyze the impact of such information on privacy of users. The main contributions are: - We analyze the spatial and social properties of human motion from real tr...
