| 摘 要： | 由于DTN网络的异步传输模式，DTN网络节点中存储着大量的冗余信息副本，导致网络拥塞．为解决这一问题，笔者在BinarySprayandWait协议的基础上提出一种主动删除冗余副本的拥塞控制策略：AAC策略，该策略通过ACK索引表及保留权值及时避免或消除拥塞现象．通过在ONE平台下的仿真模拟实验，表明该策略可以更好的提升网络吞吐量、降低丢包率、提高网络交付率等性能指标．

| Abstract: | Due to the asynchronous transfer mode of DTN, there exist a large amount of redundant information copies in the network nodes, which lead to network congestion. In order to solve this problem, this paper proposed a congestion control strategy with actively deleting redundant copies--AAC based on Binary Spray and Wait protocol. By using ACK index table and saving weights, AAC can avoid or remove congestion. The simulation experiment through ONE shows that AAC displays better performance in increasing the network throughput, reducing the packet loss rate and improving the network delivery rate. etc. |
