EFFICIENT ROUTING PROTOCOL in DELAY TOLERANT NETWORKS (Dtns)
Degree Programme in Communication Engineering MORTEZA KARIMZADEH EFFICIENT ROUTING PROTOCOL IN DELAY TOLERANT NETWORKS (DTNs) MASTER OF SCIENCE THESIS Examiners: Prof. Yevgeni Koucheryavy Dr. Dmitri Moltchanov Examiners and topic approved in the Computing and Electrical Engineering Faculty Council meeting on 6th April, 2011 II Abstract TAMPERE UNIVERSITY OF TECHNOLOGY Master’s Degree Programme in Information Technology, Department of Communication Engineering Karimzadeh, Morteza: Efficient Routing Protocol in Delay Tolerant Networks (DTNs) Master of Science Thesis, 47 pages May 2011 Major: Communication Engineering Examiners: Professor Yevgeni Koucheryavy and Dr. Dmitri Moltchanov Keywords: Delay Tolerant Networks, Opportunistic networking, Forwarding mechanism, Routing protocol, Epidemic routing, Network coding Modern Internet protocols demonstrate inefficient performance in those networks where the connectivity between end nodes has intermittent property due to dynamic topology or resource constraints. Network environments where the nodes are characterized by opportunistic connectivity are referred to as Delay Tolerant Networks (DTNs). Highly usable in numerous practical applications such as low-density mobile ad hoc networks, command/response military networks and wireless sensor networks, DTNs have been one of the growing topics of interest characterized by significant amount of research efforts invested in this area over the past decade. Routing is one of the major components significantly affecting the overall performance of DTN networks in terms of resource consumption, data delivery and latency. Over the past few years a number of routing protocols have been proposed. The focus of this thesis is on description, classification and comparison of these protocols. We discuss the state-of- the-art routing schemes and methods in opportunistic networks and classify them into two main deterministic and stochastic routing categories. -

Designs for an Internet David D. Clark Dra Version 3.0 of Jan 1, 2017 David D. Clark Designs for an Internet Status is version of the book is a pre-release intended to get feedback and comments from members of the network research community and other interested readers. Readers should assume that the book will receive substantial revision. e chapters on economics, management and meeting the needs of society are preliminary, and comments are particularly solicited on these chapters. Suggestions as to how to improve the descriptions of the various architectures I have discussed are particularly solicited, as are suggestions about additional citations to relevant material. For those with a technical background, note that the appendix contains a further review of relevant architectural work, beyond what is in Chapter 5. I am particularly interesting in learning which parts of the book non-technical readers nd hard to follow. Revision history Version 1.1 rst pre-release May 9 2016. Version 2.0 October 2016. Addition of appendix with further review of related work. Addition of a ”Chapter zero”, which provides an introduction to the Internet for non-technical readers.

I: the Conception
Excerpt from: Mayo, Keenan and Newcomb, Peter. “How the Web Was Won,” Vanity Fair, July 2008. I: The Conception Paul Baran, an electrical engineer, conceived one of the Internet’s building blocks—packet switching— while working at the Rand Corporation around 1960. Packet switching breaks data into chunks, or “packets,” and lets each one take its own path to a destination, where they are re-assembled (rather than sending everything along the same path, as a traditional telephone circuit does). A similar idea was proposed independently in Britain by Donald Davies. Later in his career, Baran would pioneer the airport metal detector. Paul Baran: It was necessary to have a strategic system that could withstand a first attack and then be able to return the favor in kind. The problem was that we didn’t have a survivable communications system, and so Soviet missiles aimed at U.S. missiles would take out the entire telephone- communication system. At that time the Strategic Air Command had just two forms of communication. One was the U.S. telephone system, or an overlay of that, and the other was high-frequency or shortwave radio. So that left us with the interesting situation of saying, Well, why do the communications fail when the bombs were aimed, not at the cities, but just at the strategic forces? And the answer was that the collateral damage was sufficient to knock out a telephone system that was highly centralized. Well, then, let’s not make it centralized. Let’s spread it out so that we can have other paths to get around the damage. -

INCIDENTAL PAPER Growing Up With the Information Age John C. B. LeGates April 2011 Program on Information Resources Policy Center for Information Policy Research Harvard University The Program on Information Resources Policy is jointly sponsored by Harvard University and the Center for Information Policy Research. Chairman Managing Director Anthony G. Oettinger John C. B. LeGates John LeGates began his career as an entrepreneur in the earliest days of computer communications and networking. He was the first to put computers in schools and later in hospitals. He built the first academic computer-resource-sharing network and was a member of the Arpanet NWG, the original Internet design team. Since 1973 he has been a member of the Harvard faculty, where he co-founded the Program on Information Resources Policy. Copyright © 2011 by the President and Fellows of Harvard College.
