Map-based direct position control system for wireless ad-hoc networks

Ad-hoc networking and mobility modelling are two very prospective research areas of modern network technologies. This paper is focused mainly on the possibilities of the map-based mobility modelling in OPNET Modeler simulation environment. The paper introduces a new simulation model which enables direct position control for mobile stations. This easily configurable and customizable system offers a promising and realistic solution to realistically model the movement of wireless stations and substitutes a testing in real environments. Since OPNET Modeler is a powerful simulation tool but it is not convenient for extensive mathematical operation, the MATLAB environment was used for calculations related to movement probabilities and destination coordinates. Both simulation environments were linked together by the MATLAB Engine library which allows external programs to access MATLAB functionalities. The proper function of system designed was evaluated by a simulation.
