Performance Improvement of Reliable Data Transfer Protocol in Broadband Satellite Networks by using the Reflecting Signals

Abstract

Satellite is the most versatile component in telecommunications systems. While it can be used for long distance telephony communications, it can provide a feasible wide-range broadcasting channel for multimedia transmissions including television broadcasting and more recently the Internet. However, a reliable link connection is necessary in order to support high-speed and reliable data transfer over the satellite channel. The satellite channel suffers from unavoidable long delay and high power attenuation. In this paper, after discussing the role and architecture of satellite networks in future multimedia networks, we show that how the traditional Go-back-N ARQ technique can be improved over the satellite link by using reflecting signals from the satellites. In the proposed scheme, we use reflecting signal from the satellite in order to investigate if the transmitting frame experiences errors. Identification of the next arriving frame is also performed during the timeout event. Through numerical and simulation results, we will demonstrate the superior performance of the proposed scheme in satellite networks.
