This book was released on 1977 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under Integrated Random-Access Reservation (IRAR) access-control schemes, newly arrived packets can be designated for reserved or random-access transmissions. In the latter case, if a collision occurs, each colliding packet is assigned for transmission by reservation, rather than attempt another random-access transmission. Performance of the IRAR schemes expressed in terms of the associated channel delay-throughput curves. Single packet messages are assumed. Analytical expressions are derived for the limiting average packet delay for a broadcast multi-access channel, under various IRAR schemes. The performance curves under IRAR access-control schemes are compared with those resulting when pure reservation and pure random-access procedures are used. It is shown that for channels with low propagation delays (such as terrestrial radio or line channels), an IRAR scheme yields an excellent performance curve over the whole throughput range. For channels with high propagation delays (such as a satellite communication channel), an IRAR scheme is shown to yield delay-throughput performance characteristics superior to those obtained under pure reservation and random-access schemes, for medium and low network throughput values. At higher throughput values, an efficiently designed integrated access control scheme will be appropriately switched from an IRAR mode into a reservation procedure.

Available in PDF, EPUB and Kindle. Book excerpt: Computer- Communication Networks presents a collection of articles the focus of which is on the field of modeling, analysis, design, and performance optimization. It discusses the problem of modeling the performance of local area networks under file transfer. It addresses the design of multi-hop, mobile-user radio networks. Some of the topics covered in the book are the distributed packet switching queuing network design, some investigations on communication switching techniques in computer networks and the minimum hop flow assignment and routing subject to an average message delay constraints. The analysis of the multi-access communication channel is covered. The local area network file transfers are discussed. The text describes the C-PODA protocol. The congestion control scheme for window flow controlled computer network is presented. A chapter of the volume is devoted to the description of a fairness control algorithm. Another section of the book focuses on the analysis of hierarchical model. The book will provide useful information to computer programmers, network analysts, students, and researchers.

This book was released on 2012-12-06 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a book about the bricks and mortar out of which are built those edifices that so well characterize late twentieth century industrial society networks of computers and terminals. Such computer networks are playing an increasing role in our daily lives, somewhat indirectly up to now as the hidden servants of banks, retail credit bureaus, airline reservation offices, and so forth, but soon they will become more visible as they enter our offices and homes and directly become part of our work, entertainment, and daily living. The study of how computer networks work is a combined study of communication theory and computer science, two disciplines appearing to have very little in common. The modern communication scientist wishing to work in this area finds himself in suddenly unfamiliar territory. It is no longer sufficient for him to think of transmission, modulation, noise immun ity, error bounds, and other abstractions of a single communication link; he is dealing now with a topologically complex interconnection of such links. And what is more striking, solving the problems of getting the signal from one point to another is just the beginning of the communication process. The communication must be in the right form to be routed properly, to be handled without congestion, and to be understood at the right points in the network. The communication scientist suddenly finds himself charged with responsibility for such things as code and format conversions, addressing, flow control, and other abstractions of a new and challenging kind.

Book excerpt: This is a book about the bricks and mortar from which are built those edifices that will permeate the emerging information society of the future-computer networks. For many years such computer networks have played an indirect role in our daily lives as the hidden servants of banks, airlines, and stores. Now they are becoming more visible as they enter our offices and homes and directly become part of our work, entertainment, and daily living. The study of how computer networks function is a combined study of communication theory and computer science, two disciplines appearing to have very little in common. The modern communication scientist wishing to work in this area soon finds that solving the traditional problems of transmission, modulation, noise immunity, and error bounds in getting the signal from one point to another is just the beginning of the challenge. The communication must be in the right form to be routed properly, to be handled without congestion, and to be understood at various points in the network. As for the computer scientist, he finds that his discipline has also changed. The fraction of computers that belong to networks is increasing all the time. And for a typical single computer, the fraction of its execution load, storage occupancy, and system management problems that are in volved with being part of a network is also growing.

This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of first and second generation wireless systems has paved the way for further research opportunities towards the next generation systems. The two standards GSM and IS-95 based on TDMA and CDMA respectively, have deeply influenced our system-level understanding, bringing new perspectives on the problems associated with wireless networks and potential for innovations. This volume presents the proceedings of the second workshop on multiaccess, mobility and teletraffic for personal communications held in May 1996 in Paris, France where some important subjects on the next generation systems have been treated. These include topics dealing with information theoretic aspects, channel modeling, diversity, interference control, resource allocation, power control, packet multi-access, stochastic modeling of mobility and traffic, and wireless network control. The selected topics in this workshop and their presented set of solutions reflect the richness of the problems in wireless communications. Indeed, development of theoretical frameworks with considerable attention to the peculiar environment of wireless communications has been the prime objective of this workshop. To elaborate, consider the problem of multi-access methods which remains a challenge for researchers. A complete evaluation of an access scheme must consider different aspects such as propagation, interference, mobility and traffic modeling. Some common bases, paradigms and models are needed. For example, today, we do not have a common archetype like the A WGN channel as in classical statistical communication. Clearly, there is a need for justified assumptions and models.

Book excerpt: Welcome to ICOIN 2005,the International Conference on Information Netwo- ing, held at Ramada Plaza Jeju Hotel, Jeju Island, Korea during January 31– February2,2005.ICOIN2005followedthesuccessofpreviousconferences.Since 1986, the conference has provided a technical forum for various issues in inf- mation networking. The theme of each conference re?ects the historic events in the computer communication industry. (Please refer to www.icoin2005.or.kr for details.) The theme of ICOIN 2004, “Convergence in Broadband and Mobile Networking,” was used again for ICOIN 2005 since we believed it was ongoing. This year we received 427 submissions in total, which came from 22 co- tries. Upon submission, authors were asked to select one of the categories listed in the Call for Papers. The most popular category chosen was network se- rity, followed by mobile networks and wireless LANs. Other areas with strong showings included QoS and resource management, ad hoc and sensor networks, and wireless multimedia systems. From the outset, we could see where recent research interest lay and could make sure that the theme was still going in the right direction.

Book excerpt: Updates from unremarked dates material used in the Institute's vacation schools at Surrey University, which over the past 15 years have become the de-facto industry standard in satellite communications. The approach concentrates on the design and planning of systems, includes little theory, and just quotes equations rather than deriving them. New material has been added on the history and background of the field; the business aspects of satellite communications; and on new applications in mobile and personal communication systems, multimedia systems, military business and small satellites, navigation, and positioning. Graduate, undergraduate, and practicing engineers should benefit from the treatment. Annotation copyrighted by Book News, Inc., Portland, OR
