Practical experiments in a satellite network environment assist in the design and understanding of future global networks. This paper describes the practical experiences gained from TCP/IP on ATM networks over a high speed satellite link and presents performance comparison studies of such networks with the same host/traac conngurations over local area (LAN) and wide area (WAN) networks. These c...

Compared with Geostationary Orbit (GEO) satellite systems and Medium Earth Orbit (MEO) satellite systems, Low Earth Orbit (LEO) satellite systems provide lower propagation delay as well as higher throughput. Because of these reasons, LEO satellite systems can play a pivotal role in providing services to areas where there is no substantial terrestrial infrastructure. In this paper, a novel kind ...

Satellite networks have signi cant advantages over terrestrial networks. Satellites provide unique advantages such as remote coverage with rapid deployment, distance insensitivity, bandwidthon-demand, immunity to terrestrial disasters, o ering broadband links. Broadband satellite networks will play an important role in the rapidly evolving information infrastructure. However, there are several ...

The family in Iran is a powerful and influential institution that is undergoing change over time. Various factors have contributed to these changes. In the 21st century, media such as satellite and cinema have linked communities closer together. In such a situation, the views, attitudes and beliefs of other societies reach out to other societies in the form of images, sounds and symbols through...

Link disruption has a considerable impact on routing in multilayered satellite networks, which includes predictable disruption from the periodic satellite motion and unpredictable disruption from communication faults. Based on the analysis on the predictability of satellite links, a link disruption routing strategy is proposed for multilayered satellite networks, where a topology period is divi...

collective behavior is regarded as one of the main issues in contemporary political sociology, a social phenomenon that has long challenged political systems. the purpose of this paper is to study the factors affecting the tendency of the students of shiraz toward collective behavior. to explain collective behavior, we have used neil smelser’s theoretical framework and from the structural-funct...

Voice over LTE (VoLTE) and NR (VoNR), are two similar technologies that have been widely deployed by operators to provide a better calling experience in 5G networks, respectively. The VoLTE/NR protocols rely on the security features of underlying LTE/5G network protect users' privacy such nobody can monitor calls learn details about call times, duration, direction. In this paper, we introduce n...

Studies have shown that packet reordering is common, especially in satellite networks where there are link level retransmissions and multipath routing. Moreover, satellite networks exhibit high corruption rates causing packet losses. Reordering and corruption of packets decrease the TCP performance of a network, mainly because it leads to overestimation of the congestion in the network. We cons...
