Abstract

Today's powerful networked personal computing devices offer a solid technical basis for mobile ad-hoc networking in support of consumer applications independent of operator networks. However,running Internet protocols directly on top ad-hoc routing protocols such as AODV requires a sufficient node density to establishend-to-end paths. In contrast, Delay-tolerant Networking (DTN) allows to exploit device capabilities also in sparse environments. In this demonstration paper, we present a DTN prototype for mobile phones as the most widespread platform for (delay-tolerant) ad-hoc networking and show a sample application that allows bypassing cellular operator infrastructure - with a fallback option incase DTN fails to deliver the information in time.
