We investigate the regularity of neighborhood status of individual users over time and justify the effectiveness of pre-adaptive strategy. To do so, we randomly choose two users, ranked respectively the 7th and the 32nd. 7 shows their neighborhood status. , the number of neighbors with larger values stays stable, and that of neighbors with smaller values decrease linearly over time. For the 32nd user, the number of users with larger values and the number of users with smaller values both decrease.

The sender is likely to be partially aware of the social behaviors and frequently-visited hotspots of the receiver. • Hotspot buffers are low-cost and can be pervasively available data storage resources [100]. They are not interconnected and will not be involved in cooperative data forwarding. They act as static receivers to temporarily store user data and allow authorized wireless access of the data when users come into their wireless communication range.
