Modeling Space-Shaped Defense Applications with Cell-DEVS

the DEVS formalism has been used as modeling and simulation technique for different natural and artificial systems. Cell-DEVS is an extension of DEVS that allows for executing cellular automata models with the advantage of evaluating the cells asynchronously with different timing delays. Both techniques have shown success in simulating space-shaped models. In this paper, we describe how they can be used to model and simulate different defense-related systems. We emphasize on using Cell-DEVS to model a land battlefield between two armies. Each army is composed of different soldiers and one flag and the goal of each army is to acquire the other’s flag. Different aspects of the soldier behavior are considered such as soldier state (alive, injured, or dead), soldier movements towards the enemy’s flag, and soldiers fight with each other. In addition, we introduce two different simulation techniques using CD++ (a toolkit developed to execute DEVS and Cell-DEVS models) showing the noticeable performance gain when using some new features introduced in the CD++ toolkit.
