Space/Terrestrial Mobile Networks Internet Access and QoS Support covers the design of a Global Mobile Broadband System (GMBS) based on the results of the European Commission's Framework Programme 5 Information Society Technologies (IST) Project SUITED. Many of the latest concept in mobility solutions, network design techniques and internet technologies are presented. The SUITED project has addressed a number of technical issues that are very much state-of-the-art. The presentation of such material in the form of a design of a real network provides a unique source of information. This book: Addresses the important topic of heterogeneous networks and the underlying tecyhnologies Describes how to design an integrated satellite/terrestrial infrastructure where all the network components are fully merged together and integrated with the Internet Core network Presents the service scenarios and system requirements of the Global Mobile Broadband System (GMBS) Discusses the necessary QoS support and defines the novel admission control scheme Gauge & Gate Reservation with Independent Probing (GRIP) Covers mobility management including Mobile-IP support and a QoS Support Module (QASM) Describes the functional and network architectures and presents signalling protocols for mobility management in GMBS Presents the design of signalling protocols and their implementation using the Specification and Description Language (SDL) Space/Terrestrial Mobile Networks Internet Access and QoS Support has an accessible and practical approach to the subject and addresses in detail, the important topic of heterogeneous networks and the underlying technologies that make this concept possible.

SPACECRAFT RELIABILITY AND MULTI-STATE FAILURES ] SPACECRAFT RELIABILITY AND MULTI-STATE FAILURES A STATISTICAL APPROACH The aerospace community has long recognized and repeatedly emphasizes the importance of reliability for space systems. Despite this, little has been published in book form on the topic. Spacecraft Reliability and Multi-State Failures addresses this gap in the literature, offering a unique focus on spacecraft reliability based on extensive statistical analysis of system and subsystem anomalies and failures. The authors provide new results pertaining to spacecraft reliability based on extensive statistical analysis of on-orbit anomaly and failure data that will be particularly useful to spacecraft manufacturers and designers, for example in guiding satellite (and subsystem) test and screening programs and providing an empirical basis for subsystem redundancy and reliability growth plans. The authors develop nonparametric results and parametric models of spacecraft and spacecraft subsystem reliability and multi-state failures, quantify the relative contribution of each subsystem to the failure of the satellites thus identifying the subsystems that drive spacecraft unreliability, and propose advanced stochastic modeling and analysis tools for the reliability and survivability of spacecraft and space-based networks. Spacecraft Reliability and Multi-State Failures provides new nonparametric results pertaining to spacecraft reliability based on extensive statistical analysis of on-orbit anomaly and failure data develops parametric models of spacecraft and spacecraft subsystem reliability and multi-state failures quantifies the relative contribution of each subsystem to the failure of the satellites proposes advanced stochastic modeling and analysis tools for the reliability and survivability of spacecraft and space-based networks provides a dedicated treatment of the reliability and subsystem anomalies of communication spacecraft in geostationary orbit.
