Abstract: Aiming at the inaccuracy in the module of MFW for OMNeT++, the function of PHY/MAC in this module is modified and mended, which implements the rate adaptation MAC protocol based on RBAB in IEEE 802.11b and a simulation model framework is constructed for cross layer network protocol stack with the modified module. An instance about cross layer design which joints rate adaptation in MAC layer and routing algorithm in network layer to improve performance of mobile Ad Hoc network is studied based on this simulation model framework. The simulation results show that cross layer design in the application of Ad Hoc network protocol stack improves the performance of Ad Hoc network significantly in the mobile wireless environments.
