Distributed Database Designs And Computation Strategies For Networked Interactive Stimulations

In real-time interactive training and simulation systems, changes of the natural terrain surface and other objects are involved. Distributed geographical database and visual simulators are being built to meet the requirements of low cost and high efficiency. In this paper, four approaches for distributing terrain databases and simulation entities across loosely coupled networks of simulators are examined. An analytical model is developed, which can be used to quantitatively estimate the performance of a distributed system. An experimental simulation study is also conducted to validate the analytical method.
