Title

Ad-hoc Storage Overlay System (ASOS): A Delay-Tolerant Approach in MANETs

Abstract

Mobile Ad-hoc NETworks (MANETs) are a type of infrastructure-less networks that are most useful in unprepared emergencies where critical applications must be launched quickly. However, they often operate in an adverse environment where end-to-end connectivity is highly susceptible to various disruptions. Methods of adjusting the motion of existing nodes or deploying additional nodes can improve the connectivity under some circumstances, but there exist scenarios where connectivity cannot be immediately improved, and disruptions must be coped with properly. In this paper we propose an architecture of the Ad-hoc Storage Overlay System (ASOS). ASOS is a self-organized overlay, consisting of storage-abundant nodes that jointly provide distributed and reliable storage to disruption-affected data flows. ASOS is a Delay-Tolerant Networking (DTN) approach that extends the conventional end-to-end data transport model in MANETs and significantly improves their applicability in practice.
