摘要
利用着色Petri网(CPN),在CPN Tools平台上建立自顶向下的分层自适应OFDMA系统接纳控制模型。该模型能直观描述系统过程,具有开放性,适用于不同算法或到达间隔与处理时间不服从指数分布的业务。采用Monitor监控器分析模型性能,并与M|M|m|n排队模型进行仿真比较,结果验证了该模型的正确性和优越性。
With the methods of Colored Petri Net（CPN） and CPN Tools platform,this paper establishes a top-down hierarchical model of adaptive OFDMA system and uses the Monitor to monitor its performance analysis.With this model,the description of the process for the system is easier to understand intuitively and on-limits,which can be applied to different algorithms.It is applies to the business that the user arrival interval and processing time are not exponentially distributed.The simulation result is compared with M｜M｜m｜n queuing model in order to verify the validity of the model.
