With the development of mobile communication networks, people are getting higher and higher requirements for network performance in the21st century. The researchers are constantly trying to use various methods to improve network performance. Ahlswed R who proposed the idea of network coding in2000, completely changed the traditional ways of communication transmission. Network coding allows intermediate

The advent of network coding broke the traditional basic operating regulation that was the pattern of storage and forwarding followed by communication network. Network coding not only reserved original function at network nodes, but also allowed coding at network nodes, which increased the transmitting capacity of the network greatly, and achieved the upper bound prescribed

Ahlswede R et al who came from the Chinese University of Hong Kong proposed the pioneering concept of network coding which changes the traditional processing way of nodes in networks.Network coding technology enables relaying nodes to encode the incoming messages before forwarding.Investigation showed that network coding can maximize the multicast capacity,save the network resources and
