Data transmission method based on hierarchical network coding
Sheng Yang · Journal of Computer Applications · 2013
In order to reduce the size of finite fields GF(2n) which was needed for the encoding calculation in intermediate node of network,a data transmission method based on hierarchical network coding was proposed in this paper.Focusing on the single-source multicast network with backbone-sub network structure,the authors decoded at the node that connected the backbone network and the sub-network.Then the decoded information was multicast to sub-network by network coding data transmission method.The theoretical analysis and the simulation results show that this method can reduce the size of finite fields GF(2n),and then reduce the computation delay of data transmission.Besides,it can make full use of the network capacity.
