Note 1: I have extracted some inter-device encounters from various reality mining datasets so they can be used with The ONE simulator for Pocket Switched Network (PSN) simulations, click this link for more details on that.

Note 2: I've also converted some datasets into the GEXF format so they can be opened with Gephi, that work is here.

There are many datasets that can be use for opportunistic network simulation and temporal network science. Here's a list.
