    Abstract: 近年來無線網路的蓬勃發展，日常生活中隨處可見的行動裝置也能夠使用無線網路進行資料的傳輸，下一代無線區域網路標802.11ax 也在2014年開始建置，其目標相較於前一代無線區域網路標準提升四倍的傳輸效能，所以未來我們勢必要使用全雙工(Full duplex)技術來因應未來對傳輸效能的要求。當使用全雙工技術時，會產生內部節點干擾問題及隱藏接收者問題，為了避免上述之問題，本論文設計具電量控制之無干擾全雙工媒介存取控制協定，透過分析干擾範圍與傳輸範圍來整理出傳輸能量對其他節點干擾影響之關係性，讓節點能完全避免內部節點干擾問題及隱藏接收者問題，大幅增加使用全雙工技術時之傳輸效能。
    Recently, IEE 802.11ax task group has started to develop a new standard for next generation wireless local area networks (WLANs) since 2014. One of goals is four times throughput improvement compared with IEEE 802.11ac. Thus, the researchers focus on full duplex (FD) communications to achieve improvement of throughput. However, there are Inter-Node Interference (INI) and Hidden Receiver Problem (HRP) in FD communications, which cause decrement of throughput. The paper analyzes the relationships among the transmission range, and interference range in case that FD is adopted and proposes an Interference Free Full Duplex with Power Control (IFFD) MAC protocol to avoid interference for next generation WLANs. IFFD cannot only prevent INI and HRP problems but also can increase network performance. Simulation results show that IFFD outperforms against other protocols in packet error rate and network throughput.
