摘要
相较于有线网络,无线网络具有误码率高、时延大、带宽低等特性。因此,考虑到TCP直接应用于无线环境的局限性,这方面的研究者们提出了多种TCP拥塞控制的改进机制,这些方案一般没有考虑误码丢包对数据发送速率的影响。本文详细的讨论了有关无线网络丢包检测的各种实施策略,并介绍了若干丢包检测技术的实现原理。
Compared with fixed networks,there are many different characteristics in wireless environments, such as relatively higher error rate, longer delay, lower bandwidth etc. Hence, many improvements of TCP congestion control mechanisms are presented. However, the influence on TCP sender＇s packet sending rate by link corruption is not considered in these improved schemes,and no perfect control mechanism for packet loss by corruption has been presented yet, This article detailed discussion the detection of packet loss in wireless network and introduced certain the detection technology of packet loss realization principle.
