An IP-ERN architecture to enable hybrid E2E/ERN protocol and application to satellite networking [PDF]
, 2012 We propose an architecture based on a hybrid E2E-ERN approach allowing ERN protocols to be inter-operable with current IP-based networks. Without introducing complex operations, the resulting E2E-ERN protocol provides inter and intra protocol fairness ...

"Internet from Space" without Inter-satellite Links
Proceedings of the 19th ACM Workshop on Hot Topics in Networks, 2020 Buoyed by advances in space technology, several firms are planning satellite constellations to offer broadband Internet service. While these developments are happening quickly, there are also many uncertainties about the design of these networks. A key open question is whether or not they will incorporate direct connectivity between satellites, instead

Reduction of the Response Time of Earth Observation Satellite Constellations using Inter-satellite Links [PDF]
, 2008 Data quality of Earth observation satellites is often evaluated in terms of short system response time and information age. Acceptable response time and information age can be achieved only by satellite constellations in LEO as they allow observations ...
