Paper Title
Analysis of Some Routing Protocols in Delay Tolerant Networks (DTNS)

Abstract
Delay Tolerant Networks (DTNs), also called as intermittently connected mobile networks, are wireless networks in which a fully connected path from source to destination is unlikely to exist. Therefore, in these networks, message delivery relies on opportunistic routing where nodes use store-carry-and-forward paradigm to route the messages. A storeand- forward transmission mechanism and a custody transfer option are among the techniques offered by DTN Bundle Protocol (BP) for dealing with challenging communication. Although the connectivity of nodes is not constantly maintained, it is still desirable to allow communication between nodes. Therefore, it is necessary to provide a routing protocol which tries to route packets throughout the times the link is available among the nodes. But this can not be done by standard routing algorithms which assume that the network is connected most of the time The routing protocols used in DTN are categorized into two group’s i.e. 1. Flooding Based and 2. Forwarding Based. Over the past few years a number of routing protocols have been proposed for DTN networks. In this paper mainly four DTN routing protocols: Direct Delivery, Epidemic Routing and Spray ,prophet and Wait Routing, are advocated and compared in terms Number of nodes Vs Delivery Probability and Buffer Size Vs Delivery Probability. Keywords - Bundle Protocol, DTNs, Intermittent Connection, Routing Protocols.
