摘要
为了探讨发送端在发送分组之前如何确定MGM(Multi-generation Mixing,MGM)网络编码的编码参数,本文提出了数据有效投递率的概念,建立了在解码成功率达到99%以上,数据有效投递率最大的准则下的线性规划.数值分析结果表明在满足MGM解码成功率的要求下,能够得到最佳的编码参数.
In order to determine the encoding parameters (mixing size, generation size, and redundancy rate) of Network Coding with Multi-Generation Mixing before sending packets, we put forward the con- cept of effective data delivery rate and discuss the problem under the condition of successful delivery probability more than 99 % and the largest effective data delivery rate. Numerical analysis results show that coding parameters can be obtained when MGM decoding success rate meet the requirements.
