Resource Reservation Protocol for Mobile Satellite Communication
The Internet Engineering Task Force is working on extending the traditional TCP/IP model for supporting multimedia and real-time applications on the Internet. Thus, new protocols have been developed such as the Resource Reservation Protocol. With the rapid growth of mobile networks, the IETF is also working on creating and extending the existing protocols to support mobile users. This has led t...
متن کاملCellular Networks, Satellite Communication 1 Satellite Communication
A satellite communications system is based on antennas in a stable orbit above the earth. Satellites serve as relay stations in the sky. The basic idea of satellite communications is that two stations on earth discuss via one or more satellites. So a little bit of satellite-related terminology: 1. Earth station is an antenna on or near the surface of the earth. 2. Uplink is a transmission from ...
متن کاملA Review: Limitations/Challenges to Earth Orbit Satellite Communication Systems
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...
متن کاملBuilding Obstruction in Satellite Mobile Communication Systems
This paper presents a simple model for the evaluation of obstruction caused by multiple buildings in satellite mobile communication systems, or in high-altitude platform (HAP) coverage. The proposed model can be useful for integration into propagation prediction tools. It is based on the KichhoffHuygens formulation, and includes the effect of ground reflections and reflections on a facing build...
متن کاملfocus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes
چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
