A SURVEY ON PREDICTION BASED ROUTING PROTOCOLS IN DELAY TOLERANT NETWORK

Abstract

Delay Tolerant Networking is a kind of technology which provides reliable communication between devices in such a network where there might not be continuous connectivity among nodes. The source to destination connectivity is not guaranteed in DTN. The store and forward capability of DTN helps to increase message delivery possibility irrespective of time taken to deliver message over normal MANET. Every Node in Network may exchange messages when they come across in transmission range of one another. The issue of Routing is very significant due to limited resources for message storage capability and forwarding mechanism. Hence the issue routing among nodes is measured by many researchers which leads to various routing protocols on the basis of Flooding and Forwarding mechanism. Hence, this paper tries to analyze various probabilistic routing protocols. The analysis presented in this paper can provide useful guidance on the design and choice of appropriate routing protocols for DTN based applications.
