| 摘 要： | 为提高水下数据传输可靠性，本文在随机线性网络编码的基础上提出一种协作数据传输算法。首先，为源节点寻找数据转发链路，让数据通过多条链路进行转发；其次，使用网络编码方法对数据包进行编码，避免转发节点转发重复数据包；最后，对各个节点的数据包传输时隙进行调度，避免节点间信号冲突。仿真结果表明，本文提出的算法在一定程度上提高了网络信道利用率和数据传输可靠性，且具有较好的稳定性。

| Abstract: | In order to improve the reliability of underwater data transmission, this paper presents a cooperative data transmission algorithm based on random linear network coding. First, the algorithm find the data forwarding link for the source node and let the data be forwarded through multiple links. Second, the network coding method is used to encode the data packets to avoid repeated data transmission. Finally, the packet transmission time slot of each node is scheduled to avoid signal conflicts between nodes. The simulation result shows that this algorithm not only improves the network channel utilization and the data transmission reliability, but also has a good stability. |
