This book was released on 2015-04-01 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Just as terrestrial networks have shifted to routed, message centric networks, the satellite networking regime is beginning to transition in the same manner. Based on established networking theories and unique orbital models, a satellite based communications network architecture is modeled that would fulfill the requirements of capacity, coverage and logistics for current and future military needs. Specifically, various satellite constellations and network characteristics are examined with a focus on how to enhance current methods of routing data in this environment. The authors explore how Social Networking theories can be applied to the routing decision making process in the space environment. Utilizing aspects of adaptation and the weak-tie relationship, an adaptive hybrid routing protocol model is proposed leveraging the predictability of orbital mechanics to increase performance and decrease network overhead.

Download or read book Range Information Systems Management Rism Phase 1 Report written by National Aeronautics Administration and published by CreateSpace. This book was released on 2014-11-17 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Aeronautics and Space Administration is investigating alternative approaches, technologies, and communication network architectures to facilitate building the Spaceports and Ranges of the future. These investigations support the Second Generation Reusable Launch Vehicle (2nd Gen RLV), and other associated craft presently under development in Government, academic, and private sectors, and provide a national centralized R&D forum for next-generation Spaceport and Range technology development. These sectors all share the common goal of changing the historic risk/reward equation for access to space, with the intent to: Dramatically reduce launch cost, Greatly improve launch system reliability, Significantly reduce crew risk. The shared and tacit goal is to achieve routine access to space. A fundamental paradigm shift is required to accomplish the desired goal. The historical approach of using dedicated and custom Range equipment situated at relatively few and widely dispersed Spaceports as the only access to space must change before routine access to space can occur. This change is analogous to the historical transformation that occurred in aviation; moving from dedicated, remote test sites where test pilots first experimented with jet-propelled aircraft to today's thriving international and regional airports. Information networks at Spaceports and Ranges must transition to a total integration of existing, new, and emerging technologies that provide a new and robust way of interconnecting the Range assets, Range operations, and Range users during the launch event. This paradigm shift must occur despite the legacy of how the networks have evolved to this point. Instead of the dedicated, immobile, inflexible information infrastructures of today's Ranges and Spaceports, a more flexible (i.e. space-based) approach is needed. Implicit in this flexibility is the need for modularization, to allow incorporation of newer technologies not yet imagined, without requiring scrapping future systems not yet even defined. The key is to envision a transition to a Space Based Range Distributed Subsystem. To accomplish this, the Range Information Systems Management (RISM) research task is providing a keen vision of both near and more distant future technologies in support of NASA's Advanced Range Technology Working Group (ARTWG) and the Advanced Spaceport Technology Working Group (ASTWG). Consistent with the goals originally identified for RISM, while supporting these working groups; this technical report details the results of researching and documenting the technical needs and technical characteristics of future Ranges, Range systems, and Range users. This report explores extant and emerging technologies and identifies the characteristics and likely requirements of a future Space Based Range Distributed Subsystem based on these technologies. This report is but the first step in implementing a future Space Based Range (SBR) Distributed Subsystem to support the Spaceports and Ranges of the future and to provide the infrastructure to enable routine access to space.

Download or read book Space Air Ground Integrated Network Security written by Jianwei Liu and published by Springer Nature. This book was released on 2023-06-19 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on security science and technology, data and information security, and mobile and network security for space-air-ground integrated networks (SAGINs). SAGIN are expected to play an increasingly important role in providing real-time, flexible, and integrated communication and data transmission services in an efficient manner. Today, SAGINs have been widely developed for a range of applications in navigation, environmental monitoring, traffic management, counter-terrorism, etc. However, security becomes a major concern, since the satellites, spacecrafts, and aircrafts are susceptible to a variety of traditional/specific network-based attacks, including eavesdropping, session hijacking, and illegal access. In this book, we review the theoretical foundations of SAGIN security. We also address a range of related security threats and provide cutting-edge solutions in the aspect of ground network security, airborne network security, space network security, and provide future trends in SAGIN security. The book goes from an introduction to the topic’s background, to a description of the basic theory, and then to cutting-edge technologies, making it suitable for readers at all levels including professional researchers and beginners. To gain the most from the book, readers should have taken prior courses in information theory, cryptography, network security, etc.

Download or read book Transfer Learning through Embedding Spaces written by Mohammad Rostami and published by CRC Press. This book was released on 2021-06-28 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent progress in artificial intelligence (AI) has revolutionized our everyday life. Many AI algorithms have reached human-level performance and AI agents are replacing humans in most professions. It is predicted that this trend will continue and 30% of work activities in 60% of current occupations will be automated. This success, however, is conditioned on availability of huge annotated datasets to training AI models. Data annotation is a time-consuming and expensive task which still is being performed by human workers. Learning efficiently from less data is a next step for making AI more similar to natural intelligence. Transfer learning has been suggested a remedy to relax the need for data annotation. The core idea in transfer learning is to transfer knowledge across similar tasks and use similarities and previously learned knowledge to learn more efficiently. In this book, we provide a brief background on transfer learning and then focus on the idea of transferring knowledge through intermediate embedding spaces. The idea is to couple and relate different learning through embedding spaces that encode task-level relations and similarities. We cover various machine learning scenarios and demonstrate that this idea can be used to overcome challenges of zero-shot learning, few-shot learning, domain adaptation, continual learning, lifelong learning, and collaborative learning.
