OPNET will be usedas a simulation tool for developing modulesneeded to define entities of the proposedarchitecture. These modules incorporate newdefined mechanisms. As an example ofmodules to be developed, we can cite the QoSnegotiation module, the transfer moduleneeded for broadcasting necessary QoS dataduring a handover and QoS context mappingmodule used to hide the diversity of radionetworks and QoS protocol integrated into theIP network.
