Guaranteed Seamless Transmission Technique for NGEO Satellite Networks

Non-geostationary (NGEO) satellite communication systems are able to provide global communication with reasonable latency and low terminal power requirements. However the highly topological dynamics, large delay and error prone links have been a matter of fact in the satellite network studies. This paper proposes a novel Guaranteed Seamless Transmission Technique(GST), which is a Hop-by-Hop scheme enhanced with the End-to-End scheme and associated with a link algorithm, which updates the link load explicitly and sends it back to the sources that use the link. We analyze GST theoretically by adopting a simple fluid model. The good performance of GST, in terms of bandwidth utilization, effective transmission ratio and fairness, is verified via a set of simulations.
