Summary:
A network simulator always is an important tool to observe and evaluate the study concept for wireless networks. If a selected simulator inherently has poor architecture, the maintenance, recondition, and expansion of functions will become more difficult and more time-consuming in the future, while it is difficult to understand and reuse by the successors. In order to make a simulator have flexible architecture and believable results, design patterns are proposed as the norms to design system architecture. A network simulator architecture is proposed, named as CCGns, which is a discrete-event virtual network simulator and follows the IEEE 802.16-2009 standard. CCGns obeys the object oriented design principles and is coded by the Java language. The main contribution includes three aspects which propose a scalable MAC messages management and the corresponding architecture, an applicable for multi-hop relay network topology architecture, and a two-stage minimum variance bandwidth allocation algorithm. By using mathematic calculation to verify the simulation results, the proposed system architecture has been proven to possess excellent fidelity.
