摘要 为推动基于网络编码的多路径路由(NCMR)可靠性传输机制的实用化,提出了一种面向无线Ad hoc网络应用的基于局部重传和网络编码的多路径路由(LR-NCMR)可靠性传输机制,在多路径路由基础上应用网络编码对数据包进行编码融合,引入重传机制在局部范围进行数据包重传.仿真结果表明,相比于已有的NCMR可靠性传输机制,新的方式能提高网络的传输可靠性,同时降低网络中的数据包冗余度. To make network coding based multipath routing （NCMR）reliability transmission mechanism more practiced, local retransmission and network coding based multipath routing（LR-NCMR） reliability transmission mechanism was proposed for wireless Ad hoc network, transmitting coded packets over mul- tipath and using retransmission within local area. Comparing with NCMR, the simulation shows that LR- NCMR is more reliable than NCMR and it can reduce the redundancy in the network.
