45706 该算法采用一种新的传染病式数据分发方法在节点不断移动的网络中分发数据，使数据能以较低的时延被网络中绝大部分节点接收到，提高了网络的可靠性； The algorithm used a new infectious data dissemination method to transmit the data, which enabled the data to be received by almost all the mobile nodes in a network with low latency and improved the reliability of the network.
45707 节点在接收到数据的同时，利用卢比变换码（LTC, Luby transform code）对数据进行编码存储， When a node receives the data, it would use LT (Luby transform) codes to encode and save them.
45708 使容量有限的节点可以保存更多的数据信息。 By this way, the nodes with limited storage spaces can save more data information.
45709 理论分析和仿真实验表明，LT-MDS 算法能够以低时延完成数据分发和存储，同时获得较高的数据持续性。 Theoretical analyses and simulations show that LT-MDS can complete the process of data dissemination and preservation with low latency, and it can achieve high data persistence.
