Message delivery in sparse Mobile Ad hoc Networks (MANETs) is difficult due to the fact that the network graph is rarely (if ever) connected. A key challenge is to find a route that can provide good delivery performance and low end-to-end delay in a disconnected network graph where nodes may move freely. We cast this challenge as an information flow problem in a social network. This paper presents social network analysis metrics that may be used to support a novel and practical forwarding solution to provide efficient message delivery in discon ....etc

INTRODUCTION
Consider a scientist who is responsible for the operation of robotic meteorological station located on the planet Mars (Fig. 1). The weather station is one of several dozen instrument platforms that communicate among themselves via a wireless local area network deployed on the Martian surface. The scientist wants to upgrade the software in the weather station s data management computer by installing and dynamically loading a large new module. The module must be transmitted first from the scientist s workstat ....etc

Abstract In this paper, we present a framework for analyzing routing performance in delay tolerant networks (DTNs). Differently from previous work, our framework is aimed at characterizing the exact distribution of relevant performance metrics, which is a substantial improvement over existing studies characterizing either the expected value of the metric, or an asymptotic approximation of the actual distribution. In particular, the considered performance metrics are packet delivery delay, and communication cost, expressed as number of copies o ....etc

ABSTRACT
Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different sets of physical and operational constraints; wide variations in transmission latency are particularly troublesome. The proposed Interplanetary Internet (IPN), which must encompass both terrestrial and interplanetary links, is an extreme case. An architecture based on a protocol that can operate successfully and reliably in multiple disparate envir ....etc

CAR: Context-Aware Adaptive Routing for Delay-Tolerant Mobile Networks

Abstract

Most of the existing research work in mobile ad hoc networking is based on the assumption that a path exists between the sender and the receiver. On the other hand, applications of decentralised mobile systems are often characterised by network partitions. As a consequence delay tolerant networking r ....etc

Improving Delay-Tolerant Network Performance Using Forward Routing Information (Java)
Proceedings of IEE INFOCOM

The development of delay-tolerant networks (DTNs) has attracted significant attention in the recent years. The concept started with the idea of interplanetary internet and later the DTN Research Group (DTNRG) took up the work concerning the architectural and protocol design principles for the DTNs. A DTN can be regarded as a group of highly disconnected networks/regions where the communication environment may be far from ideal w ....etc
