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。

Abstract: 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.
Key words: opportunistic network, data forwarding, Hybrid of Erasure Coding (H-EC)
