Udrop: Pushing Drop-Box To The Edge Of Mobile Network

Content sharing and online collaboration have become extremely popular in recent years, in particular with the pervasiveness of cloud storage services such as Dropbox. However, these popular cloud services are not accessible when users are offline and do not take the geographical location of the users into account when distributing content. Despite years of research in opportunistic content dissemination, real users are yet to fully experience the advantages of content sharing in proximity. To this end, we propose uDrop which literally pushes the cloud storage services to the edge of the network whenever interested users are in proximity of each other. uDrop enables content sharing among users in the vicinity without relying on networking infrastructure while improving the user quality of experience and reducing the cost of bandwidth. In this demonstration, we show the practical feasibility of uDrop service on Android smartphones.
