摘要

無線網路遭遇到多種獨特的問題，如低吞吐量(throughput)與低行動(mobility)支援。然而，一些無線網路所特有的性質，如傳輸媒介的廣播特性與路徑的多樣性，提供新技術在這些問題上解決的機會。利用了這些特性的網路編碼(Network coding)技術，由於其能增進網路吞吐量的優勢，近年來吸引了相當多學者的關注。本文章將介紹這些無線網路上的網路編碼技術，並探討其在無線網路上應用的可能性。

Wireless networks suffer from a variety of unique problems such as low throughput and inadequate support for mobility. However, their characteristics such as the broadcast nature of the medium, and path diversity, provide opportunities for new design principles to address these problems. Network coding which exploits these characteristics has attracted extensive attention in recent years for their elegance on improving network throughput. This article introduces these advanced wireless network coding techniques and also addresses the potential on wireless network applications.
