With the further development and extensive applications of the Internet of Things, the cellular network has become the most important transmission link and people pay more attention to establishing the network test platform. In this paper, the network test technology was analyzed, the test target and test processes were put forward, a comprehensive test platform which is used for the real sensor network traffic and simulation traffic was designed and a unified port for wireless network traffic and simulation traffic was provided. To approach to the real sensor network data, the self-similarity and long range dependence were introduced in the traffic generator, and the RMD(Random Midpoint Displacement) algorithm was used to process the simulation data to generate multi-user data models. The test environment would be chosen respectively in this article according to the requirement to establish a unified test platform with two different test interfaces, which could satisfy different demands and provide guide and references to the cellular network test.
