【 摘 要 】

A data Publish/Subscribe method with network coding (DPS-NC) used in delay tolerant network is proposed. Based on the publish/subscribe mechanism, the topic data were encoded and transmit with random network coding method, which can take full advantage of the network capacity to multicast. At the same time, for working out the problem of large data redundancy and vast invalid de-liveries in the network coding broadcast process, a packet routing scheme based on ant colony algorithm was brought. In the end, some simulation experiments are carried out and results show that the DPS-NC method can get better delivery performance.
