Based On The P2P To The Application And Analysis Of Network Coding

Network Coding theory was first proposed by R.Ahlswede in 2000, and it has made a great improvement both in theory and practice. Network Coding is a new kind of revolutionary network communication technology, which enables coding process before data transmitting on nodes,and provides the equality and substitutability for data on the transmitting process in network. These advantages can enhance the efficiency of file sharing systems.In this paper, we study the framework of linear network coding based on the analysis of network coding theory and P2P networks. Then, we introduce the combination of the sparse coding and the generation encoding. Meanwhile, to analyze the performance of our scheme, we discuss the detailed aspects in encoding and decoding. Our work mainly focuses on the following aspects: Firstly, we introduce the definition of linear network coding and discuss the policy of sparse coding and generation coding in network coding theory. Then, we combine the advantages of sparse coding and generation coding, and introduce our scheme. Finally, we test the performance of our scheme and analyze the efficiency of encoding and decoding. The experimental results show the advantages of the combination of sparse coding and generation coding.
