Scalable data fusion using Astrolabe

The dramatic growth of computer networks creates both an opportunity and a daunting distributed computing problem for users seeking to perform data fusion and data mining. The problem is that data often resides on large numbers of devices and evolves rapidly. Systems that collect data at a single location scale poorly and suffer from single-point-failures. Astrolabe performs data fusion in real-time, creating a virtual system-wide hierarchical database, which evolves as the underlying information changes. A scalable aggregation mechanism offers a flexible way to perform data mining within the resulting virtual database. Astrolabe is secure, robust under a wide range of failure and attack scenarios, and imposes low loads even under stress.
