Beschreibung
Resource Management in Satellite Networks: Optimization and Cross-Layer Design addresses the emergent research area of cross-layer air interface design for satellite systems. A detailed analysis of cross-layer methods is presented along with new analytical and simulation results demonstrating that these techniques can assures high QoS levels for differentiated traffic classes. The research presented integrates the expertise of a wide range of researchers, and addresses all aspects of system design (e.g., propagation issues, resource management techniques, link design, QoS, transport protocols, etc.). Of particular importance is the inclusion of research applicable to both fixed and mobile satellite systems.
Resource Management in Satellite Networks: Optimization and Cross-Layer Design is based on the work of the SatNEx Network of Excellence. Since its inception in January 2004, SatNEx has focused on the investigation of cross-layer design issues, which have since emerged to form a distinct field of research. More than 14 partner organizations and institutions participated in this research.This book will serve as a reference for systems engineers and satellite network engineers as well as researchers and graduate students in the field of satellite communications.
Nowadays, satellites are used for a variety of purposes, including sensors and data collection, weather, maritime navigation and timing, Earth observation, and communications. In particular, satellite transmissions have an important role in telephone communications, television broadcasting, computer com- nications as well as navigation. The use of satellites for communications was a brilliant idea of Arthur C. ClarkewhowroteafamousarticleinOctober1945intheWirelessWorldjo- nal, entitled “Extra Terrestrial Relays - Can Rocket Stations Give Worldwide Coverage?” that described the use of manned satellites in orbits at 35,800 km altitude, thus having synchronous motion with respect to a point on the Earth. This article was the basis for the use of GEOstationary (GEO) sat- lites for telecommunications. Subsequently, he also proved the usefulness of satellites as compared to transatlantic telephone cables. Satellite communications deserve the special merit to allow connecting people at great distances by using the same (homogeneous) communication system and technology. Other very signi?cant advantages of the satellite - proach are: (i) easy fruition of both broadcast and multicast high bit-rate multimedia services;(ii)provision ofbackupcommunication servicesforusers on a global scale (this feature is very important for emergency scenarios and disaster relief activities); (iii) provision of services in areas that could not be reached by terrestrial infrastructures; (iv) support of high-mobility users.
