Abstract

In this work we study WLAN traces from five different sources and focus on investigation of encounter patterns between users. We find that typical wireless LAN users encounter with a small portion of the whole population (no more than 60% in all traces, and on average between 1.88% to 6.70%). Total encounters of MNs follow BiPareto distribution. These few encounters are sufficient to build a connected relationship network, which is a Small World graph. We further investigate the potential of node-to-node information diffusion, and find that the richness of encounter pattern provides a reliable platform on which information diffusion without infrastructure is feasible and robust.
