A Content Freshness Enhancement With Infrastructures in Mobile Opportunistic Networks

In mobile opportunistic networks, the authors investigate the effect of infrastructures on content update process. In the network, an information provider continuously generates a time sensitive content (e.g., news, twits or military commands) whose freshness decreases with time. This information is propagated to users throughout opportunistic contacts. Users prefer to have the more recently generated (i.e., up-to-date) content. In that, they utilize a content age to compare their freshness and share only the smaller age content when an opportunistic contact occurs.
