针对无线传感器网络中的多重故障，提出了一种基于线性网络编码的可靠通信方法。为了实现这一目标，我们设计了一个确定性的LNC计划RDLC的基础上，平均数的路径故障同时发生在网络中的其他路径故障的最大数量。与传统方法相比，该方案可以显著提高网络吞吐量。在我们的研究中，我们还研究了随机线性码RRLC在无线传感器网络中提供可靠通信的潜力，并证明了RRLC可以提供可靠通信的概率的下界。最后，进行了大量的仿真实验，结果表明所提出的LNC方案的有效性。
We address the modeling and design of linear network coding (LNC) for reliable communication against multiple failures in wireless sensor networks (WSNs). To fulfill the objective, we design a deterministic LNC scheme RDLC based on the average number of path failures simultaneously happening in the network other than the maximum number of path failures. The scheme can significantly improve the network throughput comparing with the traditional approaches. In our study, we also investigate the potential of random linear code RRLC for providing reliable communication in WSNs and prove the low bound of the probability that the RRLC can provide the reliable communication. Finally, extensive simulation experiments have been conducted, and the results demonstrate the effectiveness of the proposed LNC schemes.
