Simple movement and detection in discrete event simulation

Many scenarios involving simulation require modeling movement and sensing. Traditionally, this has been done in a time-stepped manner, often because of a mistaken belief that using a pure discrete event approach is infeasible. This paper discusses how simple motion (linear, uniform, two-dimensional) and simple sensing can be modeled with a pure discrete event approach. We demonstrate that this approach is not only feasible, it is often more desirable from several standpoints.
