摘要
在移动自组网络中,由于攻击或者链路失效使网络产生的拓扑变化往往会导致数据传输的中断,而信道共享和多跳特性也使得机密性难以得到保证。针对Ad hoc网络端对端的可靠数据传输,提出了基于多路径路由的多路数据传输模式,重点研究了数据分割和在多路径上的数据分布问题。通过并行传输、适度数据冗余和校验计算相结合,以及容错的数据分布,增强了数据传输的鲁棒性和机密性。
In Ad hoc network, the data transmitting may interrupt because of topology change caused by attack or link disconnection, and besides, the characteristic of channel sharing and multi-hop affected the confidentiality. Aimed at the dependable end-to-end data transmitting in Ad hoc network, this article bring forward a multiplex forwarding mode based on multi-path routing. We chiefly study the data striping and dispensing on the multi-paths, by parallel transmission, appropriate data redundancy, with checking out, and fault tolerance data distribution, the novel data transmission mode enhances robustness and confidentiality.
