One-to-one modeling and simulation of unbounded systems: experiences and lessons

Conventional computer modeling and simulation have focused on computer objects that represent elements of the real world. In this paper we present a new approach to modeling and simulation in which authors describe the characteristics of the world being simulated without specifying how they are to be represented as computer objects. This approach is enabled by the EASEL modeling and simulation system (EMSS). Furthermore, this approach does not assume global visibility and centralized control, which are inherently inaccurate assumptions for unbounded systems (in which participants have incomplete or imprecise information about the system as a whole). Because this approach allows models to be one-to-one with the real world, models should be more accurate and simulations more realistic. The discussion includes the challenges faced in the modeling and simulation process of the distance vector IP routing protocol over a large-scale communications network, and the language features intended to address these problems.
