摘　　要：针对H-EC数据转发机制所存在的系统漏洞问题,提出了一种有效解决系统漏洞的方法,同时提出了一种对数据块进行有效划分的方法。在此基础上,设计并实现了一种新的数据转发机制——增强混合擦除编码机制(EH-EC)。在OMNET++下的仿真结果表明:EH-EC时延更少,转发成功率更高,但是相对H-EC会增加少量的路由信息冗余。An efficient method was proposed to solve the system black hole problem existed in Hybrid of Erasure Coding(H_EC).And at the same time an original method was proposed to divide messages into small data blocks.Based on these,a new forwarding approach called Enhanced Hybrid Erasure-Coding(EH-EC) was proposed and achieved.Theoretical analysis and simulation results show that messages can be transmitted by EH-EC from source node to destination node with lower delay and higher delivery rate than H-EC by the OMNET++ platform,but only a few router redundancies will be increased.
