Population Based Routing in LEO Satellite Networks

Packet switching in a Low Earth Orbit (LEO) satellite network may calculate the best traffic route through the less populated areas of the planet, in order to avoid relaying through the busiest satellites. A number of ideas for route calculation in a LEO system have been evaluated and the performance results are presented. This paper reports from ongoing research on Space Information Networks (SIN) with the purpose to offer application services in a LEO satellite network to mobile users. The conclusion is that route calculation based on population density gives a moderate, but significant improvement in resource utilization.publishedVersio

A Scalable and Fault Tolerant Architecture for Distributed Web Resource Discovery

Most Internet search engines are built on a centralised design, and will therefore not cope with the expected future growth in information and query volume. A distributed approach to Internet resource discovery seems necessary. Many distributed designs have been proposed, but their scaleability is largely unknown. We propose a distributed design based on the use of classified metadata, which can be proven to be extremely scaleable, and has interesting fault-tolerant properties. We will show the principles of this design, called the Content- Sensitive Infrastructure (CSI), and demonstrate its properties through formal analysis and simulation
