It proposed a data dissemination mechanism with network coding based on ant colony algorithm (DDM-NC)

used in multi-source multi-sink delay tolerant network (DTN).Based on the publish/subscribe mechanism

the topic data were computed and transferred using network coding method

which can take full advantage of the network capacity to multicast

to improve security and efficiency of the transfer process.At the same time

for working out the problem of large data redundancy and vast invalid deliveries in the packages broadcast process

a package routing scheme based on ant colony algorithm was brought up

to guide the packages deliver to destinations

and cut down the data redundancy and deliver latency.The simulation results show that

compared with the traditional DTN epidemic routing and random network coding method

the DDM-NC method can get better data delivery performance.
