"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
