The Research And Implement Of Cooperative Relay Network Coding System Performance Testing Platform

In the communications network system, whether it is a wired communication network system or a wireless communication network system, the information which from the source node needs to be transmited by relay node. But people generally consider that a relay node just play a simple role which has the only function of data forwarding when it is transmitted by the communications system, instead of doing other data processing. This view was greatly changed until the concept of network coding proposing as well as the development of the network coding technology.Network coding thchnology combines the routing and coding, thus the network node is capable of both data forwarding function namely routing function, and data transminting function after it is encoded. However, in the actual network coding implementation, where the performance has been changed of the cooperative relay system using this technology with respect to the system that do not use it, and how to display the performance improvement, it is a key issues of concern. In this paper, by learning of the relay and network coding technology, and the data transfer processing of the actual relay system, we use the MFC technology to design and develop the testing platform which based on the performance of the cooperative relay network coding system.This paper has an analysis about physical layer and MAC layer data processing mechanisms of different cooperative relay systems which using network coding technology. And it designs and realizes the testing platform. These jobs depend on the brief researching and analysis about the actual relay system as well as the overall architecture of the network coding system. The realization part consists of two parts, the first one is the design and achievement of the platform which realizes the function of data receiving and processing, and this part has a description about the specific functions and operations as well as the test results. The second part is the realization of data interactive function between the testing platform and the system. This part based on the first one, and it increases the data transmission function, so it allows the system to interact data with the testing platform, and achives the purpose of system testing, and completes the verification of the correctness and effectiveness about the actual solutions of the relay network coding system.
