中文摘要 本論文針對同頻全雙工無線區域網路(In-Band Full Duplex Wireless LANs, IBFD WLANs)中,全雙工所造成的節點間干擾問題,提出有效的解決策略。近年來,隨著無線區域網路的快速發展,為了因應大量裝置的傳輸需求,許多研究提出可以在相同頻道中同時發送與接收資料的全雙工技術。雖然近年來隨著技術的進步,全雙工的自我干擾問題可以被有效地解決,但仍存在節點間的干擾問題。因此本論文提出一種新的媒體存取控制機制,用於解決因全雙工所造成的節點間干擾問題。此機制藉由發送封包的方式,來檢測是否有節點間的干擾問題。此機制可以有效的避免干擾所產生的接收失敗問題,藉此達到全雙工效能的提升。最後,通過模擬實驗結果,採用我們所提出的機制與傳統全雙工相比,效能平均提高了約20%
英文摘要 This paper proposes an effective solution strategy for inter-node interference to the performance degradation caused by In-Band Full-Duplex Wireless LANs (IBFD WLANs). In recent years, the rapid development of wireless networks, in order to cope with the transmission requirements of a large number of devices, many studies have proposed full-duplex technology that can simultaneously transmit and receive data in the same channel. Although in recent years, the advancement of technology, the problem of full-duplex self-interference can be effectively solved, but there is still a problem of interference between nodes. Therefore, this paper proposes a new media access control mechanism to solve the problem of internode interference caused by full duplex. This mechanism detects whether there is interference between nodes by sending a packet. This mechanism can effectively avoid the reception failure problem caused by interference, thereby achieving the improvement of full-duplex performance. Finally, the simulation results, the performance of our proposed mechanism is improved by about 20% on average compared to the traditional full-duplex.
