总结了具有代表性的竞争式MAC接入协议：冲突避免多址接入MACA、IEEE 802.11 DCF和信道获得多址接入FAMA传输介质访问控制接入的一般性规律，建立了一个竞争式MAC接入数学模型，研究哪些因素影响网络通信。通过NS2网络模拟实验，验证了这些影响的存在，并初步了解如何减少这些负面影响。与无线网络物理层或高层网络比起来，MAC接入对于无线网络高效可靠通信的负面影响容易被忽略，实际却存在，该研究对无线网络可靠通信具有一定参考价值。
總結瞭具有代錶性的競爭式MAC接入協議：遲突避免多阯接入MACA、IEEE 802.11 DCF和信道穫得多阯接入FAMA傳輸介質訪問控製接入的一般性規律，建立瞭一箇競爭式MAC接入數學模型，研究哪些因素影響網絡通信。通過NS2網絡模擬實驗，驗證瞭這些影響的存在，併初步瞭解如何減少這些負麵影響。與無線網絡物理層或高層網絡比起來，MAC接入對于無線網絡高效可靠通信的負麵影響容易被忽略，實際卻存在，該研究對無線網絡可靠通信具有一定參攷價值。

A contention MAC access model is built by concluding general rules of representive contention MAC access protocols: Multiple Access Collision Avoidance,IEEE 802.11 DCF and Floor Acquisition Multiple Access. The factors influencing the networks communication are studied by the model. These negative influences existence are tested by networks simulation. The pilot method reducing these is acquired on NS2. MAC access bad effects on wireless networks high effeciency and reliability are easily ignored but indeed existed compared with physical layer and higher layer than MAC layer. So the study has some reference to the wireless networks reliable communication.
