Mac protocols in satellite communication

mac protocols in satellite communication A channel access method is also based on a multiple access protocol and control mechanism, also known as media access control (mac) media access control deals with issues such as addressing, assigning multiplex channels to different users, and avoiding collisions.

Abstract in order to overcome the shortcomings of existing medium access control (mac) protocols based on tdma or cdma in satellite networks, interleave division multiple access (idma) technique is introduced into satellite communication networks. 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. This requires a media access control (mac) protocol, ie a principle for the nodes to take turns on the channel and to avoid collisions common examples are csma/cd, used in ethernet bus networks and hub networks, and csma/ca, satellite communications edit.

Etsi's activities concerning satellite communications include satellite communication services and applications (including mobile and broadcasting), earth stations and earth station equipment, especially the radio frequency interfaces and network and/or user interfaces and protocols implemented in earth stations and satellite systems. In the open systems interconnection model of communication, the media access control layer is one of two sublayers of the data link control layer and is concerned with sharing the physical connection to the network among several computerseach computer has its own unique mac address ethernet is an example of a protocol that works at the media access control layer level.

In ieee 802 lan/man standards, the medium access control (mac) sublayer (also known as the media access control sublayer) and the logical link control (llc) sublayer together make up the data link layer. In these cases, the mac protocol can consist in the creation and assignment of orthogonal channels via frequency, time, code, space multiplexing, or any combination thereof [7,9.

With the development of leo satellite communication, it is the basic requirement that various kinds of services will be provided considering that weak channel collision detection ability, long propagation delay and heavy load in leo satellite communication system, a valid adaptive access control protocol aprma is proposed. 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. Abstract: 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, and a novel idma-based mac protocol is proposed in this paper due to the potential advantages. Satellite communications (satcom) plays a vital role in the global and communication protocols intended to increase safety and ensure a rapid and automated response from authorities and emergency services in the mac, or linux, the firmware is more heterogeneous there are many components. The local network addresses used in ieee 802 networks and fddi networks are called media access control addresses they are based on the addressing scheme that was used in early ethernet implementations a mac address is intended as a unique serial number.

Mac protocols used by wireless sensor networks and a general method of performance evaluation standards for wireless communications exist for different applications: cellular telephony, satellite communications, broadcast radio, local area networks, and so forth forming a scatternet the mac protocol uses polling with a time division.

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. Analysis and simulation results show that, by taking full advantage of the chip-by-chip multi-user detection technique, the proposed idma mac protocol achieves high throughput and low average packet delay simultaneously, with low onboard processing complexity in the multi-beam satellite communication systems. 1 performance evaluation of a mac protocol for atm over satellite tolga örs and barry evans centre for communication systems research, university of surrey, guildford, surrey gu2 5xh, uk.
