摘要
网络编码是一种提高网络吞吐量和性能的新技术,预计将成为未来网络的一项关键技术。本文概述了无线网络中的网络编码技术,无线网络被认为是网络编码最可能得到应用的领域之一,网络编码技术使无线媒质的广播属性可以得到充分利用,无线网络和传感器网络为网络编码的应用提供了巨大的机会。本文结合不同无线场景介绍了网络编码的各种编码方法,包括传统的网络编码、物理层网络编码、模拟网络编码以及复数域网络编码,并对未来发展给出了展望。
Network coding is a novel technique to improve network throughput and performance.It is expected to be a key technology for networks of future.This paper gives a survey on the network coding applicated in wireless networks which is considerd to be one of the most likely applications of network coding.Network coding allows to take advantage of the broadcasting nature of the shared wireless medium.Wireless networks and sensor networks provide opportunities for the application of network coding.In this paper,we introduce several network coding and corresponding encoding strategies under different scenarios.These include traditional network coding,physical layer network coding,analogue network coding and complex field network coding as well.We also give remarks on wireless network coding in the future.
