DISTRIBUTED DATABASE DESIGNS AND COMPUTATION STRATEGIES FOR NETWORKEDINTERACTIVE STIMULATIONS

In real-time interactive training and simulation systems, changes of t he natural terrain surface and other objects are involved. Distributed geographical database and visual simulators are being built to meet t he requirements of low cost and high efficiency. In this paper, four a pproaches for distributing terrain databases and simulation entities a cross loosely coupled networks of simulators are examined. An analytic al model is developed, which can be used to quantitatively estimate th e performance of a distributed system. An experimental simulation stud y is also conducted to validate the analytical method. (C) 1995 Academ ic Press, Inc.
