全双工自适应选择式ARQ协议设计

文中在标准全双工选择式ARQ滑动窗口协议的基础上设计了一种具有多种自适应措施的全双工选择式ARQ协议，并在此设计的基础上给出了相应的算法。该设计针对长距离点对点无线通信的特点。采用了可变的数据帧长，重发计次以及自适应多次确认等多种自适应措施，经过理论分析和实际测试都表明，该设计能够在长RTT延时和强干扰的通信条件下实现高效可靠的数据传输。

Design and Realization of Self-adaptive Duplex Selective ARQ Protocol

In this paper, a self - adaptive full - duplex selective ARQ protocol and its corresponding algorithm were presented for the wireless long distance point - to - point communications. On the basis of classic duplex ARQ sliding window protocols, the new protocol adopted several self - adaptive measures including variable packet length, retransmission count and multi - acknowledge. The analysis and experiments showed that these measures could improve the efficiency under the conditions of a long RTT and severe disturbance.
