摘要:
网络编码是通信网络中信息处理与传输技术研究的重要热点.目前关于网络编码的研究多集中在提高网络吞吐量方面,在提高数据可靠性方面也逐渐得到重视.文中以提高数据传输可靠性为目的,以网络编码为基础,构造基本的对等设备之间数据传输模型,结合传感器网络特有的通信机制及无线链路广播传输的特性,理论分析了数据通过网络编码后能够正确传输的概率.通过仿真可以看出网络编码在信噪比较低的条件下可以明显提高数据传输可靠性
Abstract:
Network coding is an important topic in signal processing and transmission. Most research of network is focused on improving the output of network,besides,more and more attention is paid on the impact on improving reliability of the data transmission. In order to improve the reliability of data transmission,based on network coding,propose a point-to-point model for the communication of two end devices and analyze the probability of data correct transmission with network coding based on WSN and wireless broadcast. The simula-tion result indicates that network coding can promote the reliability of the data transmission in low SNR situation
