Utilizing Satellite Systems for Mobile Communications: An Emerging Approach
2009
The future trends of technologies are to achieve all systems in an integrated global one that offers all the services in a simple way. The proposed mobile communications over satellite is an advanced technology that used the facilities and benefits of both systems to achieve competitive services. The proposed system concentrated on a global system that served the entire world and gives some specialization and privacy for each country. This paper attempts to show how to implement mobile communications over satellite systems in an efficient, flexible, and cost-effective manner.

We are delighted to bring to you this special issue on satellite communications, which we have prepared as part of the spreading of excellence remit of the satellite communications network of excellence (SatNEx). The SatNEx project, which began in 2004, is funded for five years under the European Union's Sixth Framework Programme (FP6) Information Society Technologies (IST) Thematic Area. Led by the German Aerospace Center, SatNEx brings together a network of 24 partners, distributed throughout Europe, with membership drawn from ten countries.
A Survey on Mobile Satellite Systems
International Journal of Satellite Communications and Networking, 2010
Satellite systems represent a significant solution to provide communication services to mobile users in under-populated regions, in emergency areas, on planes, trains, and ships. In all these cases, satellite systems have unique capabilities in terms of robustness, wide area coverage, and broadcast/multicast capabilities. This paper surveys current mobile satellite networks and services from different standpoints, encompassing research issues, recent standardization advances (e.g. mobile extension for DVB-S2/-RCS, DVB-SH) and some operational systems (e.g. Globalstar, Inmarsat BGAN, Iridium, and Thuraya). The last part of this paper is devoted to qualitative and quantitative comparisons of the different mobile satellite systems to understand their characteristics in terms of services, capacity, resource utilization efficiency, and user mobility degree.
To provide ubiquitous terrestrial Internet coverage mobility and Internet-based access to data generated by satellites, there is a strong desire to integrate the terrestrial Internet and satellite networks. This requires satellites that are based on IP for communications. Rotation of low Earth orbit satellites around the Earth results in communicating with different ground stations over time, and requires mobility management protocols for seamless communication between the Internet and satellite networks. In this article we provide a comprehensive summary and comparison of state-of-the-art research on mobility management schemes for satellite networks. The schemes are based on network and transport layers for managing host and network mobility. This article clearly indicates the aspects that need further research and which mobility management schemes are the best candidates for satellite networks.

Connection admission control (CAC) is an important element for quality of service (QoS) provisioning in wireless networks, such as IEEE 802.16 standard, which is also known as worldwide interoperability for microwave access (WiMAX). While the standard defines PHY and MAC requirements, CAC is left to the vendors to design and implement for service differentiation and QoS support. In this paper a Quadra-Threshold (QT) CAC scheme is proposed for IEEE 802.16 networks. The proposed CAC considers four different thresholds for the four connection types namely, UGS, ertPS, rtPS and nrtPS services. The QT scheme is used to prioritize each connection type for service differentiation and QoS support. A performance analysis model based on Markov chains is proposed and numerical results are presented to demonstrate the performance of the proposed scheme. The scheme when compared with complete partitioning scheme performs better in terms of blocking probability.
Network design consideration of a satellite-based mobile communications system
1986
The concept o f mobile communications via a geosynchronous satellite has been proposed in recent years. Twelve companies have filed applications with the Federal Communications Commission to offer nationwide Mobile Satellite Services (MSS). Chis paper addresses several technical issues related to MSS from the network design point o f view. MSAT-X, which stands for the Mobile Satellite Experiment, is the task assigned to the Jet Propulsion Laboratory by the United States National Aeronautics and Space Administration to develop low-cost, spectral-efficient, satellite-based mobile communications technologies for 1990's. A1 though the discussions and recommendations presented in this paper are 1 imi ted to MSAT-X, technologles developed under MSAT-X may be o f the utmost importance to the first generation MSS. with the National Aeronautics and Space Administration.
