随着对物联网技术的深入研究和广泛应用，蜂窝网络已成为其最重要的传输链路，而建立相应的网络测试平台也越来越受到人们的重视。文章对网络测试技术进行了分析，提出了测试指标和测试流程，设计了支持实际传感网业务和仿真业务的综合测试平台，并且为无线传感网业务和仿真业务提供了统一的接口。同时设计了业务发生器，引入自相似和长相关保证仿真业务更接近实际传感网数据，并使用 RMD(Random Midpoint Displacement)算法生成具有相关性的多用户业务模型。文章根据需求选择测试环境，建立统一的测试平台，集成了两种测试接口，满足不同条件的测试，为测试蜂窝网络提供了指导和借鉴。

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 trafifc and simulation trafifc was designed and a uniifed port for wireless network trafifc and simulation trafifc 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 uniifed test platform with two different test interfaces, which could satisfy different demands and provide guide and references to the cellular network test.
