网络编码调度策略的研究

网络编码是通信领域的一项重大突破,其基本思想是建立在网络信息流的基础之上,通过网络节点对来自不同链路的信息流进行编码处理,使其既能实现传统路由功能,又能实现对信息的编码处理。分析了等速率的网络编码调度策略,并把自适应传输技术应用到网络编码的调度策略,然后通过Matlab仿真分析,验证了自适应的网络编码策略可提高通信系统的网络编码增益、吞吐量和减少数据传输延时方面的贡献。

Study on Network Coding Scheduling Strategy

Network coding is a major breakthrough in the field of communication,whose basic thought is on the network information flow,which makes the network nodes not only realize the traditional routing function,but also realize the encode information by allowing network nodes combine the information from different links.The equal rate network coding scheduling strategy is analized,and adaptive transmission technology is applied to network coding scheduling strategy,it is verified that the adaptive network coding scheduling strategy can improve the communication system network coding gain and throughput by the Matlab simulation,and the strategy is proved to reduce the transmission delay of the data packet.
