Advanced mobility models for ad hoc network simulations

Abstract

It is well known that mobility modeling plays an important role when assessing the performance of MANET protocols during a simulation test. This paper presents a tool to generate realistic mobility traces for MANET simulations. A new mobility model called AMADEOS was developed as an extension for the CANUMobisim framework. To model mobility for simulation environments, a new mobility model was created that takes into account obstacles. AMADEOS makes it easy and fast to automatically generate realistic mobility. It allows to edit spatial environments with polygonal obstacles to he used within simulations. It also allows to visualize an animation of the generated mobility traces. A new propagation model based on ray tracing was also implemented as part of AMADEOS.
