Worldwide usage of the Internet is currently growing atan exponential rate, resulting inadrainatic increase in thedemandfortiie transmission of Internet data via satellite. The TCP/IP protocol suite, which forms the basis of the Internet, performs sub-optimally when confronted with a geostationary satellite link. This may result in poor perj40rmance as seen by an interactive user and/or ine&ici...

The TRANSAT [1] satellite architecture is intended to provide efficient Internet access services over DVB-RCS satellite links. One of the key features in the TRANSAT architecture is the Satellite-Link Aware Communication Protocol (S-LACP), which operates at the link layer, and is employed over a satellite segment to decrease the residual packet error rate down to an acceptable level. In this si...

The rapid growth of Internet-based applications pushes broadband satellite networks to carry on IP traffic. In previously proposed connectionless routing schemes in satellite networks, the metrics used to calculate the paths do not reflect the total delay a packet may experience. In this paper, a new Satellite Grouping and Routing Protocol (SGRP) is developed. In each snapshot period, SGRP divi...

This paper describes the main characteristics and architecture of a satellite mobile internet access (MSIA) system developed by ETRI. MSIA system provides Internet service, broadcasting, and digital A/V service in both fixed and mobile environments using Ku-band geostationary earth orbit (GEO) satellite. A Ku -band two-way active phased array antenna installed on top of the transportation vehic...

Distributed applications and transport protocols communicating over a satellite link may react very strongly to conditions specific to that kind of link. Providing an evaluation framework to allow tests of real implementations of such software in that context is quite a challenging task. In this paper we show how the use of the general-purpose KauNet IP-level emulator combined with satellite-sp...

Ka band, the 20/30 GHz frequency band for satellite communications, has gained much interest in recent times. It is well suited for applications with small sized earth stations. The major disadvantage of Ka band, however, is its sensitivity to rain fading. Several satellite experiments are being carried out at the moment studying so called adaptive fade countermeasures, the purpose of which is ...

Real-time multimedia applications impose strict delay bounds and are sensitive to delay variations. Satellite link handover increases delay jitter and signaling overhead as well as the termination probability of ongoing connections. To satisfy the QoS requirements of multimedia applications, satellite routing protocols should consider link handovers and minimize their effect on the active conne...

Inter-Satellite communication link is the important method to set up the link between satellites in different earth orbits such as lower, medium and geosynchronous. It is an innovative technique in which laser is used to transmit data from one end to another. In this paper, we have deliberated a presentation of different challenging issues in achieving a extended inter satellite link for an IsO...

A new routing algorithm for MPLS(Multi-Protocol Label Switching, MPLS)traffic engineering in SDN-based (Software Defined Network, SDN)satellite switching networks is presented in this paper. LSP(Label Switched Path, LSP)link initial weights are defined as composite functions consisting of link transmission delay, residual bandwidth and BER(Bit Error Rate, BER). Based upon ISL(Inter-Satellite Li...

in this paper satellite wave propagation at ku and ka band is considered. the design and simulation of a typical satellite beacon receiver at ka band is designed and simulated for the future works. also rain attenuation prediction at ku band using satellite signal beacon measurement and simulations for iran telecommunication research center (itrc) are presented. the measurement setup consists o...
