Satellite Networks

Satellite networks will play an important role in our future information-based society. However, satellite communications introduce a new set of research problems in computer networking and distributed applications. In essence, satellite links have fundamentally different properties than terrestrial wired or wireless networks. These include larger latency, bursty error characteristics, asymmetric capability, and unconventional network architecture. These difference have far-reaching effects on many internetworking and distributed computing issues.

From 1995 to 2000, we built a strong research program at HRL in the area of satellite-based internetworking and distributed computing applications (I was the technical lead). We collaborated globally with many universities, research labs, and other organizations like IETF. Our work has benefited the industry including Boeing, Hughes, and U.S. Government (DARPA and NASA).
