This book provides a novel method based on advantages of mobility model of Low Earth Orbit Mobile Satellite System LEO MSS which allows the evaluation of instant of subsequent handover of a MS even if its location is unknown. This method is then utilized to propose two prioritized handover schemes, Pseudo Last Useful Instant PLUI strategy and Dynamic Channel Reservation DCR-like scheme based respectively on LUI and DCR schemes, previously proposed in literature. The authors also approach a different aspect of handover problem: calls with short durations dropped due to a handover failure. We propose a decision system based on fuzzy logic Rescuing System that allows the rescue of calls with short durations facing a premature at the expense of those lasting for long durations.

This book is supposed to serve as a comprehensive and instructive guide through the new world of digital communication. On the physical layer optical and electrical cabling technology are described as well as wireless communication technologies. On the data link layer local area networks (LANs) are introduced together with the most popular LAN technologies such as Ethernet, Token Ring, FDDI, and ATM as well as wireless LAN technologies including IEEE 802.x, Bluetooth, or ZigBee. A wide range of WAN technologies are covered including contemporary high speed technologies like PDH and SDH up to high speed wireless WANs (WiMAX) and 4th generation wireless telephone networks LTE. Routing technologies conclude the treatment of the data link layer. Next, there is the Internet layer with the Internet protocol IP that establishes a virtual uniform network out of the net of heterogeneous networks. In detail, both versions, IPv4 as well as the successor IPv6 are covered in detail as well as ICMP, NDP, and Mobile IP. In the subsequent transport layer protocol functions are provided to offer a connection-oriented and reliable transport service on the basis of the simple and unreliable IP. The basic protocols TCP and UDP are introduced as well as NAT, the network address translation. Beside transport layer security protocols like SSL and TLS are presented. On the upmost application layer popular Internet application protocols are described like DNS, SMTP, PGP, (S)FTP, NFS, SSH, DHCP, SNMP, RTP, RTCP, RTSP, and World Wide Web.

The past 50 years have witnessed a revolution in computing and related communications technologies. The contributions of industry and university researchers to this revolution are manifest; less widely recognized is the major role the federal government played in launching the computing revolution and sustaining its momentum. Funding a Revolution examines the history of computing since World War II to elucidate the federal government's role in funding computing research, supporting the education of computer scientists and engineers, and equipping university research labs. It reviews the economic rationale for government support of research, characterizes federal support for computing research, and summarizes key historical advances in which government-sponsored research played an important role. Funding a Revolution contains a series of case studies in relational databases, the Internet, theoretical computer science, artificial intelligence, and virtual reality that demonstrate the complex interactions among government, universities, and industry that have driven the field. It offers a series of lessons that identify factors contributing to the success of the nation's computing enterprise and the government's role within it.

A History of the Internet and the Digital Future tells the story of the development of the Internet from the 1950s to the present and examines how the balance of power has shifted between the individual and the state in the areas of censorship, copyright infringement, intellectual freedom, and terrorism and warfare. Johnny Ryan explains how the Internet has revolutionized political campaigns; how the development of the World Wide Web enfranchised a new online population of assertive, niche consumers; and how the dot-com bust taught smarter firms to capitalize on the power of digital artisans. From the government-controlled systems of the Cold War to today’s move towards cloud computing, user-driven content, and the new global commons, this book reveals the trends that are shaping the businesses, politics, and media of the digital future.

Communications via satellite introduces a number of new technical problems for mobile networks and applications. Satellite links have fundamentally different properties from terrestrial wired or wireless networks. Some of the properties include larger latency, bursty error characteristics, asymmetric capability, and unconventional network architecture. These differences have far-reaching effects on many satellite communication issues. Internetworking and Computing over Satellite Networks's emphasis is on data networking, internetworking and distributed computing issues. The material surveys recent work in the area of satellite networks, introduces certain state-of-the-art technologies, and presents recent research results in these areas. A variety of issues involving applications, network architecture, medium access controls, multicast routing, asymmetric routing, transport protocols, TCP performance enhancement techniques, data broadcast, and information disseminations, are addressed. This is one of the first books to be focused on the internetworking and computing aspect of satellite networks. Internetworking and Computing over Satellite Networks will be enormously useful to students, engineers, and researchers in satellite-related data communication networks. It will also serve as a strong reference work for graduate students in advanced computer networks and distributed systems study.
