【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]:In order to promote the practicability of the reliability transmission mechanism of multipath routing based on network coding, a reliability transmission mechanism based on local retransmission and network coding for wireless Ad hoc network applications is proposed. On the basis of multipath routing, network coding is used to encode and fuse data packets, and retransmission mechanism is introduced to retransmit packets in local range. The simulation results show that compared with the existing NCMR reliability transmission mechanism, the new method can improve the transmission reliability of the network and reduce the redundancy of data packets in the network.
