Kun Hao, Zhigang Jin, Beibei Wang

With the advent of information age, a large number of new multifarious information services are emerging, and requirements for information services are increasing. Hence, usersÂ’ experience quality has become an important academic research topic. The appearance of network coding provides a new method for improving QoE. This paper pays much attention on how to utilize network coding technology for improving transmission efficiency of media streaming and heterogeneous network, and how to establish QoE protection mechanism of TCP. We compared TCP/NC with TCP Reno and TCP Vegas using network simulator NS-2, the experimental results show that the TCP/NC is effective and network coding is useful to improve QoE
