Abstract
In austere environments, satellite communication is the only practical option for telemedical backhaul. Supporting telemedical applications over low earth orbit (LEO) and geosynchronous orbit (GEO) satellite communications links requires a detailed analysis of how the characteristics of these links impact telemedical applications. This thesis aims to show if the characteristics of LEO or GEO satellite communications are better suited to support telemedicine in an austere environment. This is done by comparing the performance of medical application traffic over LEO, GEO, and terrestrial internet service provider links to show how different link characteristics impact network traffic. Terrestrial internet service provider links are used as a baseline for comparison because most applications perform optimally on high-speed terrestrial communication links. The analysis uses objective data to show that non-interactive and non-delay tolerant applications perform better on a GEO link, while interactive non-delay tolerant, interactive delay-tolerant traffic, and non-interactive delay tolerant traffic all perform better on LEO links. This work reveals that the protocol stack for telemedical applications can be selected or designed to optimize performance over LEO satellite communication links, but GEO links add latency impacts to interactive communication that cannot be mitigated.
