A Conceptual Simulation Framework For Mobile Radio Communications: A Flexilevel Approach

Mobile radio communications systems are attracting more and more attention since they provide a means for users on the move to exchange information with other stationary or mobile stations. The capability of communication on the move can support many services and create lots of applications. For example, in the future Intelligent Vehicles Highway Systems (NHS), mobile communication technologies have enabled two important subsystems, namely Advanced Traffic Management and Information Systems (ATMIS) and Automatic Vehicular Control Systems (AVCS). The purpose of this research is to develop a modeling simulation framework for the radio communications networks in ATMIS. The framework is expected to be able to help system designers understand the key parameters in designing the radio communications system by performing analyses and simulations. After the key system parameters are identified, the system performance then can be traded off against costs such as RF bandwidth and system complexity. Though most of the modeling concepts can be carried over to AVCS, our discussion will be focused on ATMIS.
