Abstract

We present an architecture for scalable DTN communication in sparsely populated areas. Our approach is based on Uni-DTN, a unidirectional DTN convergence layer that we have developed for unicast and multicast distribution of DTN bundles. In this paper, we discuss possible application scenarios, present a suitable distribution architecture and the Uni-DTN convergence layer and describe, how specific features of the DTN bundle specification and DTN communication scenarios can be implemented using Uni-DTN.
