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.

关键词: 无线网络, 可靠性传输, 随机网络编码, 冗余度, 局部重传

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.

Key words: wireless Ad hoc network, reliability transmission, random network coding, redundancy, local retransmission
