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.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced.

  • Syllabus – Internet and Web Journalism
    Syllabus – Internet and Web Journalism 1. Internet –Introduction, History, evolution and development, The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to research commissioned by the federal government of the United States in the 1960s to build robust, fault-tolerant communication with computer networks. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The linking of commercial networks and enterprises by the early 1990s marks the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia since the 1980s, the commercialization Incorporated its services and technologies into virtually every aspect of modern life. Most traditional communications media, including telephony, radio, television, paper mail and newspapers are reshaped, redefined, or even bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, and video streaming websites.

  • 1 What Is the Internet (And What Makes It Work)
    What Is The Internet (And What Makes It Work) - December, 1999 By Robert E. Kahn and Vinton G. Cerf In this issue: INTRODUCTION THE EVOLUTION OF THE INTERNET THE INTERNET ARCHITECTURE GOVERNMENT S HISTORICAL ROLE A DEFINITION FOR THE INTERNET WHO RUNS THE INTERNET WHERE DO WE GO FROM HERE? This paper was prepared by the authors at the request of the Internet Policy Institute (IPI), a non-profit organization based in Washington, D.C., for inclusion in their upcoming series of Internet related papers. It is a condensation of a longer paper in preparation by the authors on the same subject. Many topics of potential interest were not included in this condensed version because of size and subject matter constraints. Nevertheless, the reader should get a basic idea of the Internet, how it came to be, and perhaps even how to begin thinking about it from an architectural perspective. This will be especially important to policy makers who need to distinguish the Internet as a global information system apart from its underlying communications infrastructure. INTRODUCTION As we approach a new millennium, the Internet is revolutionizing our society, our economy and our technological systems. No one knows for certain how far, or in what direction, the Internet will evolve. But no one should underestimate its importance. Over the past century and a half, important technological developments have created a global environment that is drawing the people of the world closer and closer together. During the industrial revolution, we learned to put motors to work to magnify human and animal muscle power.

As a result, web-browsing is slow. Because users frequently pay for each minute that they are connected, browsing the web can be an expensive proposition. In these places, what is needed is a communication protocol that can provide reliable end-to-end data delivery even in the face of episodic connectivity and low-bandwidth routes.

Lievrouw, Chair Technological time has been a topic of much theorization and dread, as both intellectuals and laypeople fear that human life is increasingly becoming secondary to the technological world. Feelings of despair and nihilism, perhaps attributable to social, political and economic upheavals brought by the synchronization of human life with technology, have been theorized by numerous scholars in a plethora of overlapping disciplines. What is left undertheorized is how technology develops in ways that might or might not actually foster these sensations of synchronicity, or speed. Technological development includes patterns of social coordination and consumption, as well as individual use and goals, that all relate to a sense of lived time. But what of the ways that technical design fosters these relations? What is the discourse of time in technological projects? This dissertation investigates the aforementioned questions in the context of NSF-funded Future Internet Architecture (FIA) projects—Named Data Networking (NDN), eXpressive Internet Architecture (XIA), and Mobility First (MF)—which are currently underway.
