全双工（FD）通信可以使点对点的吞吐量增加一倍，将其应用到多跳网络中，可以提高网络的吞吐量。为了在网络中实现这些优点，有必要设计用于FD通信的介质访问控制（MAC）协议。开发FD多跳网络的分析模型不仅对开发最优协议设计而且对澄清这种网络动态是有效和有用的。本文给出了串拓扑无线FD多跳网络的解析表达式。为了实现这一点，空中通话时间的表达式的解析模型，这是有效的分析方法，在半双工多跳网络，和马尔可夫链模型的FD MAC相结合。该模型是第一个分析模型的字符串拓扑FD多跳网络。该模型可以计算任意跳数和任意负载大小的FD多跳网络的端到端吞吐量。通过与仿真结果的比较，验证了解析表达式的正确性。通过与半双工（HD）多跳网络中的结果比较，证实了FD通信在多跳网络中的有效性。
Full-duplex (FD) communication can double point-to-point throughput, By applying the FD technique to multi-hop networks, the throughput enhancing is expected. For achieving the benefits in the networks, it is necessary to design medium access control (MAC) protocol for FD communications. Developing an analytical model for FD multi-hop networks is effective and useful for not only developing the optimal protocol design but also clarifying such network dynamics. This paper proposes analytical expressions for string-topology wireless FD multi-hop network. For achieving that, analytical model of airtime expressions, which is effective analytical approach in a half-duplex multi-hop network, and Markov-chain model for FD MAC are integrated. This model is the first analytical model for string-topology FD multi-hop networks. End-to-end throughput of FD multi-hop network for any number of hops and any payload size can be obtained from the proposed model. The analytical expressions are verified by comparisons with simulation results. From the comparison with the results in half-duplex (HD) multi-hop network, the effectiveness of FD communication in multi-hop networks are confirmed.
