Routing Enhancement Specific to Mobile Environment Using DTN

Hemal Shah and Yogeshwar P. Kosta

Abstract—A communications network that withstands long delays or outages and is capable of storing packets temporarily stationed in intermediate nodes, until an end-to-end route is re-established or regenerated is known as a delay tolerant network or in short DTN. This paper aims to consolidate general & basic aspects relating to information needs to efficiently execute DTN routing. We start by presenting the evolution of some routing protocols, spotting few routing schemes relevant to us, discuss their groups and classifications, their operating network environment, and through critical study and observation, to identify specific parameters that are common across relevant schemes associated with routing that helps to bring out the advantage and disadvantage associated with them in an attempt to establishing some possible future extensions-of-the-existing through consolidation - accomplished by capturing, organizing and showcasing the same in metrics and proposing new schemes as well. This leads us to identify specific schemes such as controlled replication and techniques that will help us to exploit the delay and utilize the time judiciously to improve the overall efficiency of information exchange in a DTN network. The essence of this study being; to utilize efficiently the temporal period (delay) by opportunistically establishing connectivity - in a strategic manner, to help exchange information across by locally distributed resources, thus making optimal use of available network resources and enhancing the efficiency of information exchange.

Index Terms—Forwarding, replication, single-copy, multiple-copy, relay, delivery ratio, delay, throughput, local resource, Routing techniques, routing efficiencies, protocol
