Mac protocols in satellite communication

Medium access control protocols for space and satellite communications: a survey and assessment h peyravi computer science program department of mathematics and computer science. A communication satellite functions as an overhead wireless repeater station that provides a microwave mac protocols for satellite links satellite channels have some unique characteristics that require special considerations at the dlc (data link control) layer of the osi model the satellite links are often referred to as long fat pipes. Media access (mac) protocols there are many communication channels, including radio and acoustic channels, and certain kinds of wired links (coaxial cables), where multiple nodes can all be connected and hear each other’s transmissions (either perfectly or with some non-zero probability. Lan and mac protocols introduction satellite communication provides a bridge cappyability to exchange frames b/w two different mac protocols.

How to cite suzuki, t and tasaka, s (1993), a comparison of construction methods for mac and llc protocols in satellite packet communication networks. In this paper, we focus on specific protocols or methods guiding access to the medium used for transmission and retransmission of packets (messages) to and from the satellites these protocols are referred to as medium access schemes medium access control (mac) schemes are mechanisms for sharing a single link [2. Keywords- fdma, mac, protocols, satellite, satellite communication refers to radio-link (microwave line of sight) communication using one or more radio frequency retransmitters located at great distances from the terminal earth stations the use of satellite in communication systems has become so.

Medium access control protocols performance in satellite communications abstract: medium access control protocols are at the core of all forms of electronic communications systems mac protocols are designed to coordinate the transmission of packets, retransmission of damaged packets, and resolution of collisions among stations during a contention period.

A mac layer is not required in full-duplex point-to-point communication, but address fields are included in some point-to-point protocols for compatibility reasons channel access control mechanism the channel access control mechanisms provided by the mac layer are also known as a multiple access protocol. Request pdf on researchgate | a novel mac protocol for idma-based multi-beam satellite communication systems | summary considering the limitations of satellite communication systems and advantages. Mac protocols for satellite links satellite channels have some unique characteristics that require special considerations at the dlc (data link control) layer of the osi model the satellite links are often referred to as long fat pipes they represent paths with high bandwidth-delay product.

Satellite communications, a valid adaptive aprma mac protocol was proposed different access probabil- ity functions for different services were obtained and appropriate access probabilities for voice and data users. 5 satellite communication is employed in remote sensing for prospecting natural resources as well as monitoring atmospheric conditions 6 three communication satellites situated at the geostationary altitude and spaced 120 degrees apart could interconnect over 90% of the earth 7 a satellite communication network is easily expandable. In order to overcome the shortcomings of existing mac protocols based on tdma or cdma in satellite networks, idma technique is introduced into satellite communication networks for the first time.

Communication systems, vol 23, no 4, pp 485-506 1 uw-mac: an underwater sensor network mac protocol mohamed k watfa1, samir salmen2 and hovig denkilkian3 computer science department 1,2, electrical & computer engineering department 3 previously proposed mac protocols for wireless sensor networks aim at minimizing the energy. The media access control (mac) data communication networks protocol sub-layer, also known as the medium access control, is a sub-layer of the data link layer specified in the seven-layer osi model the medium access layer was made necessary by systems that share a common communications medium typically these are local area networks.

  • This paper discusses the layered construction of the osi second layer (data link layer) in the satellite packet communication network from the viewpoint of the system performance the isolated-type system, where the media access control (mac) sublayer and logical link control (llc) sublayer are defined independently, and the combined-type.
  • Many researchers employ ieee802154 as communication technology for wireless sensor networks (wsns) however, medium access control (mac) layer requirements for communications in wireless sensor networks (wsns) vary because the network is usually optimized for specific applications.
  • Mac protocols are foundations in low-level network architecture and play a significant role in the performance of higher-level protocols such as multiservices and multimedia application protocols in this article five classes of mac protocols are investigated with respect to their applications in satellite communications.

Media access (mac) protocols there are many communication channels, including radio and acoustic channels, and certain kinds of wired links (coaxial cables), where multiple nodes can all be connected ployed for data communication was a satellite network: the alohanet.
