摘 要:基于网络编码的无线传输技术是一个新兴的、高度集成的领域,目前涉及多个学科的综合知识。它包含大量节点,甚至将数千个节点集中在控制无线传输网络系统的监视器上。分布广泛的节点由于环境的多样性和能量的消耗而存在故障发生的可能。本文中笔者针对无线传输技术网络能量和通信容量的限制,提出了一种将多径传输与网络编码相结合的技术,将其引入到无线传感器网络中,以平衡网络负载,整体降低能耗,延长网络生命周期。并且就基于网络编码的无线传输技术进行分析。

Abstract:Wireless transmission technology based on network coding is a new and highly integrated field,and now it involves multiple disciplines and comprehensive knowledge. It contains a large number of nodes,and even thousands of nodes are concentrated on the monitor of wireless transmission network system. The widespread distribution of nodes is possible due to environmental diversity and energy consumption. In this paper,aiming at the limitation of network energy and communication capacity of wireless transmission technology,a technology that combines multipath transmission and network coding is proposed,which is introduced into wireless sensor network to balance network load,reduce energy consumption as a whole and prolong life cycle of network. And this research mainly focuses on the analysis of wireless transmission technology based on network coding.
Keywords:network coding;wireless transmission technology;research

基于網络编码的无线传输技术包括多个方面,可指通过无线电波自由空间的无线信号传输、所有类型的非有线通信以及无线电功率无人造导体的电能传输。编码是一种数学技术,可用于提高网络的吞吐量、效率可量测性以及抵御攻击和窃听等而不是简单地将收到的信息节点网络分成几个分组并将其组合在一起进行传输。这可用于获得最大值信息。
1 网络编码系统的分析
1.1 网络编码示例体系
网络编码示例体系通常用于说明其如何优选择途径。两个源节点具有必须传输到两个目的地节点的信息,这两个目的地节点各自边缘只能携带单个值。如果只允许使用路由,则中心链路只能承载单个系统,而不能同时承载两者。假设我们使网络编码体系经过中心;……
