The authors propose a system that makes opportunistic use of mobile computing devices and ad-hoc networking to provide a transient storage service to clients in a localized geographical region. It is assumed that mobile devices are autonomous i.e. their mobility patterns are individually determined and not under the control of a central entity. The main challenge is to offset the potential data loss caused by node mobility with inter-node communication. They first argue, on the basis of simulation and theory that such a service is feasible, given a sufficiently high density of mobile devices.
