| 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.

| Abstract: | 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 multipath 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. |
