The modeling of mobility for a collection of wireless devices operating over a large area is a formidable task as it involves many degrees of freedom such as network topology, local densities and speed and so, much of the work in this area focuses on imposing assumptions on mobility which make the models somewhat artificial. On the other hand, a detailed model of mobility in the context of radio propagation represents a significant challenge. Therefore, the authors adapt a cellular automaton model to reduce the mobility problem to its simplest form whilst maintaining the essential features. A simulation model including the main attributes of radio propagation is developed. It is used to understand the relationship between communication, interference and mobility in the context of ad-hoc networks.
