Abstract

Two scaling problems face the Internet today. First, it will be years before terrestrial networks are able to provide adequate bandwidth uniformly around the world, given the explosive growth in Internet bandwidth demand and the amount of the world that is still unwired. Second, the traffic distribution is not uniform worldwide: Clients in all countries of the world access content that today is chiefly produced in a few regions of the world . A new generation of Internet access built around geosynchronous satellites can provide imme ....etc

Improving the Performance of TCP Over Wireless Links

In this thesis, we address the problem of degradation in performance of TCP over wireless links. We propose enhancements to TCP so that it responds to certain control signals from the network. These control signals allow TCP to differentiate packet losses unrelated to congestion from those related to congestion. This enables TCP to react appropriately to different packet losses resulting in improved performance. We developed a network simulator for evaluating the performance of our ....etc

Abstract

While channel coding is a standard method of improving a system’s energy efficiency in digital communications, its practice does not extend to high-speed links. Increasing demands in network speeds are placing a large burden on the energy efficiency of high-speed links and render the benefit of channel coding for these systems a timely subject. The low error rates of interest and the presence of residual intersymbol interference (ISI) caused by hardware constra ....etc

Abstract.
We examine the utility of Light-Emitting Diodes (LEDs) for short-range intersatellite links (ISLs), and compare and contrast LEDs with existing laser technologies used for long-distance ISLs. A hypothetical low-end LED ISL page link is described, and applications are suggested
