MEDIUM ACCESS CONTROL PERFORMANCE IN SATELLITE COMMUNICATION

ABSTRACT

MAC protocols are designed to coordinate the transmission of packets, retransmission of damaged packets, and resolution of collisions among stations during a contention period . The MAC protocols include fixed assignment protocol, demand assignment protocol, random access protocol, reservation protocol, hybrid of reservation protocol and random access protocols and adaptive protocols. Satellite communication systems have traditionally been designed for voice traffic. Multiple access protocols for conflict resolution have typically been channel-oriented with either fixed or demand assignment. Data communications, however, have much more diverse traffic characteristics and transmission requirements than voice communications. An access protocol suitable for wideband pack satellite network serving a finite number of bursty buffered users is proposed. The performance of the proposed scheme is evaluated and is compared with other protocols. Different stratergies for making reservations are considered. The performance criteria include high channel throughput, low transmission delay, channel stability and low complexity.

INTRODUCTION

The MAC sublayer provides addressing and channel access control mechanisms that make it possible for several terminals or network nodes to communicate within a multiple access network that incorporates a shared medium, e.g. Ethernet. The hardware that implements the MAC is referred to as a medium access controller.
The MAC sublayer acts as an interface between the logical link control (LLC) sublayer and the network 's physical layer. The MAC layer emulates a full-duplex logical communication channel in a multi-point network. This channel may provide unicast, multicast or broadcast communication service.

FIXED-ASSIGNMENT MULTIPLE ACCESS PROTOCOLS

In fixed-assignment multiple access protocols, the allocation of channel bandwidth to a station is a

    SATELLITE COMMUNICATIONS SATELLITE COMMUNICATIONS - AN OVERVIEW INTRODUCTION The outer space has always fascinated people on the earth and communication through space evolved as an offshoot of ideas for space travel. The earliest idea of using artificial satellites for communications is found in a science fiction Brick Moon by Edward Evert Hale, published in 1869-70. While the early fictional accounts of satellite and space communications bear little resemblance to the technology as it exists…

    History of Satellite Communications The first idea of satellite communication came from an article in 1945 named Wireless World, where Author C. Clarke described the use of manned satellites in 24 hour orbits to distribute television programs. However, the first person to carefully evaluate the technical and financial aspects of such a venture was John R. Pierce of Bell Telephone Laboratories (Whalen, n.d.). In a 1954 speech and 1955 article, Pierce described the usefulness of a communications…

    Satellite communication, in telecommunications, is the use of artificial satellites to provide communication links between various points on Earth. Satellite communications play a vital role in the global telecommunications system. Approximately 2,000 artificial satellites orbiting Earth relay analog and digital signals carrying voice, video, and data to and from one or many locations worldwide. Satellite communication has two main components: the ground segment, which consists of fixed or mobile…

    In 1945 Arthur C. Clarke wrote an article entitled "The Future of World Communications" for the magazine Wireless World. This article, which the editors renamed "Extra-Terrestrial Relays", was published in the October issue. In it Clarke described the properties of the geostationary orbit, a circular orbit in the equatorial plane of the earth such that a satellite appears to hover over a fixed point on the equator. The period of revolution is equal to the period of rotation of the earth…

    Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts, which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols, speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999, the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly…
