Global connectivity cannot be guaranteed by terrestrial networks due to the lack of infrastructure in rural areas. Neither can satellite networks assure this due to lack of signal penetration and capacity coverage issues in densely populated areas. To bridge this gap, we propose an Orthogonal Frequency Domain (OFDM) based hybrid architecture where users are provided service by existing mobile n...

Satellite ATM networks have significant advantages over terrestrial ATM networks. Satellites provide unique advantages such as remote coverage with rapid deployment, distance insensitivity, bandwidth on demand, immunity to terrestrial disasters, and offering broadband links, Satellite ATM networks will play an important role in the rapidly evolving information infrastructure. However, there are...

Support of elastic TCP traffic over broadband GEO satellite networks v control algorithm for TCP flows over split-TCP satellite networks that can preserve the target requirements in terms of TCP steady-state throughput and TCP latency. We describe generic fixed-point approximations for the performance of TCP flows in geostationary satellite networks. We provide examples for the method applicabi...

Satellite networking is different from wired or wireless networks. TCP/IP performance and behavior with respect to normal wireless network and wired networks are different from one another. As the architecture of TCP/IP protocol was not designed to perform well over high-latency or noisy channels and so its performance over satellite networks are totally different. The properties of satellite c...

Low Earth Orbit (LEO) satellite networks will play an important role in the evolving information infrastructure. Satellites in the low earth orbits provide communication with shorter end-to-end delays and efficient frequency usage. However, some problems need to be solved before LEO satellite systems can be successfully deployed. One of these problems is the handover management. The objective o...

This letter proposes a new mechanism that supports adaptive sending control using Real-Time Streaming Protocol (RTSP) and Transmission Control Protocol (TCP) for IPTV service over heterogeneous networks. The proposed mechanism is implemented on a mobile IPTV device and its performance is verified for providing seamless television watching in heterogeneous networks, even when in motion. key word...

This document outlines possible TCP enhancements that may allow TCP to better utilize the available bandwidth provided by satellite networks. The algorithms and mechanisms outlined have not been judged to be safe for the global Internet. However, the mechanisms may be appropriate for private satellite networks (or other long-delay network paths). The goal of this document is to educate research...

Low earth orbit (LEO) satellite systems gained considerable interest in the past decade and were expected to be instrumental in future telecommunications systems. Nevertheless, the first two LEO satellite networks that are currently in operation have not come to fruition on account of the limited spectrum of services that they provide. In this context, future LEO satellite networks will be gear...
