A Satellite-LTE Network with Delay-Tolerant Capabilities: Design and Performance Evaluation
Marica Amadeo, Giuseppe Araniti, Antonio Iera, Antonella Molinaro · 2011
In this paper, a delay tolerant approach for traffic management in LTE over satellite link is presented. Due to the long propagation delays and frequent disruptions, mobile satellite communications pose many challenges, especially to the transport layer when the TCP protocol is used. We design and evaluate the performance of a transport protocol solution based on the DTN architecture in the satellite-LTE system. Our proposal, named Tiny Bundle Layer, acts as an overlay on top of different versions of TCP in order to overcome the satellite link impairments.
