说明：  分析OPNET仿真環境中現有的無線信道建模方案,針對其在多信道仿真中的問題,提出一種新的無線信道建模方案,以彌補原有方案在節點進行信道切換時無法實時偵聽信道狀態的缺陷,保證動態多信道環境中物理載波偵聽的實時性.通過對無線自組織網絡多信道MAC層協議的仿真及仿真數據的分析,驗證了新方案適用于多信道網絡的場景仿真.
(Analysis of the existing simulation environment OPNET wireless channel modeling programs, for its multi-channel simulation problem, a new wireless channel modeling program to make up for the original program channel switching node can not be real-time channel state listener defects, ensure that the dynamic multi-channel environment, the physical carrier sensing in real time. Through the multi-channel wireless ad hoc network MAC layer protocol simulation and analysis of simulation data to verify a new program for simulation of multi-channel network scenarios.)
