Routing in mobile delay-tolerant networks faces new challenges such as mobility and the dynamic nature of the network. Social network information may be useful for routing since mobile nodes in the same social network may be encountered more often and thus be more successful at message-passing. Collecting this social network information, however, can be challenging. Authors compare a social network traced from user encounters with a user-declared social network, and show some of the differences between these two networks. As mobile devices, carried by individuals in their everyday lives, become more prevalent, it may be useful to investigate how authors can exploit human mobility and proximity in the context of mobile device routing.
