Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: In recent years low earth orbit (LEO) satellites have begun to attract much attention. This attention is largely due to their relatively small propagation delays (5̃ to 10ms) when compared with that of geostationary earth orbit (GEO) satellites (1̃20 ms). However, due to the inherent nature of a LEO satellite network, transmissions very often require hopping through a large number of satellites. Anytime that a transmission must travel through a number of nodes we must consider the processing delay of each node when calculating the end-to-end delay. This thesis analyzes and observes that the total delay experienced in a LEO satellite network can sometimes result in a longer end-to-end delay than routing through a GEO satellite network. We thus proposed a hybrid satellite network of LEO and GEO satellites that might best minimize end-to-end delays. Both a LEO and a hybrid system were designed and simulated using Network Simulator (NS). The results show much smaller end-to-end delays (e.g., 46%) when transmitting through our hybrid satellite network than a strictly LEO satellite network.
Download or read book Worldwide Advances in Communication Networks written by Bijan Jabbari and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The symposium on "Worldwide Advances in Communications Networks" which was held on May 14-15, 1992 at GMU was an ambitious attempt to bring together leaders in the communications area to discuss the major issues in this rapidly-changing technology. The symposium was a success and many of the ideas presented at the conference are being implemented. This proceeding contains the majority of the papers presented at the symposium and abstracts of the remainder. The papers may be divided into seven general categories. The first five papers explore some important design issues for high speed networks (gigabit networks). Traffic modelling, quality of service guarantees, switching alternatives, and routing are discussed. The next two papers focus on applications for broadband communications. Weinstein begins by asking, "ARE THERE ANY APPLICATIONS?" and then proceeds to develop a wide variety of potential uses. Personick concentrates on multimedia applications. The next three papers deal with Personal Communications Services (PCS) and the notion of communicating with anyone, at any time, anywhere. Several of the key technical issues such as CDMA vs TDMA are analyzed in detail. The fourth area is satellite communications. Two papers discuss some of the major changes that are taking place and potential new systems. The next two papers discuss signal coding and digital video. Jayant provides an excellent overview of the impressive capabilities that are available for the compression of speech, audio, image, and video signals. Bellisio concentrates on video encoding.

Available in PDF, EPUB and Kindle. Book excerpt: This cutting-edge resource provides a comprehensive treatment of applying delay-tolerant networking (DTN) principles to satellite-based network communications. Detailed models and analytical tools are used to evaluate performance and provide guidance in the field. This book presents the state-of-the-art in existing on-board and ground technologies that support satellite applications, such as communications protocols, algorithms, and security procedures. Readers gain key insight into the fundamental concepts of DTN applied to satellite networks (DTSNs) and case studies are provided. This book presents an authoritative introduction to the methods for computing metrics for satellite network modeling. Satellite communications are examined, including satellite links, communication protocols, and distributed multiple access schemes, such as time division, code division, and frequency division. This book focuses on ways in which DTN might make terrestrial communication and observation via earth orbiting satellites less expensive and more robust. The fundamental concepts and analysis of the Ring Road Architecture are explored. Unique analyses on the motivating factors of using Inter-Satellite Links (ISL) to form networks in disruptive environments in space are discussed. This book explores the limits of larger and complex DTSNs as the number of satellites increase and different orbital formations become possible. As satellite networks become larger in upcoming years this book provides a guide for readers to stay informed about standard protocols such as DTN that will allow seamless interoperation, cost reduction, and risk mitigation.
