| The interaction of communication and Internet technology has created many new applications, which also brought many problems at the same time. In order to improve the network performance, the researchers have studied the algorithms, When analyzing and proving the new designed network scheme, the network simulation platform which satisfies all kinds of requirements is needed, but the popular simulation tools like MATLAB and NS2 can not meet the needs of VMIMO system in the project because of their application limitations, a special distributed simulation system is proposed to solve the problem , the main contents of this paper are listed as follows: 1. The research issues of the simulation system are collected and analysed,based on the system requirement analysis ,and also considering feasibility analysis of research problems, the working principle and system prototype of the simulation system is made and the basic elements is designed.2. The cooperation of the simulation system is analyzed, then the standard development of the network communication is researched, the mechanism of quick resource sharing the efficient protocol on the communication between different platform and the different functional modules is designed, at last, the work process of the system is described in detail and the source code is written.3. Study the IEEE 802.11 MAC design the data structure, module partition and work flow ,then the code are also written.4. Study the service convergence sub layer of IEEE 802.16,design data structure as well as work flow and write code.Based on the principles such as reliability, stability, visualization and easy using, the simulation system is developed with programming language which combined with the standard template library. All modules of the simulation system like events scheduling system, call stack system ,data communication program and so on are closely integrated to complete simulation analysis and verification. |
