The invention discloses an opportunistic routing-based inter-flow network coding method and device, and a storage medium. When a node receives a data packet, a candidate set list and a corresponding priority parameter of the data packet are read, and whether the node is in the candidate set list is determined. And then, when the node does not receive the ACK frame of the node with the higher priority, the node is responsible for forwarding the data packet according to a priority selection principle. And when another node in the Mesh network obtains the data packet sending opportunity, the coding condition is detected, and coding and forwarding preparation are carried out. According to the method, after the inter-flow network coding is introduced, the expected number of times of transmission of data packets by two nodes in the wireless Mesh network can be effectively reduced, so that the network forwarding success rate and the network throughput are improved. 本发明公开一种基于机会主义路由的流间网络编码方法、设备及存储介质。本发明中节点收到一个数据包时，读取数
