摘要在最近几年，物联网发展迅速，在智能家居、智能交通、智能医疗、智能电网、智能物流、智能农业、智能电力、智能工业等方面得到充分应用。
物联网的通信性能主要有网络生存时间、数据传输速率、传输延时等，本文主要结合实际的应用场合，分析这些方法提高性能的原因。最后通过在MC13213无线通信模块上实验测试，观察在不同通信距离、有无简单握手协议、不同发射功率和不同通信信道情况的实验结果，对现有的协议进行了归纳。同时在实验中应用到了ZigBee技术，分析对比了同一节点在不同环境条件下的性能情况，对物联网的通信性能有了更深一步的了解和认识。66671

Title Analysis and test of the Internet of things
Abstract
In recent years, the Internet of Things is developing rapidly. It is wildly used and plays an important role in smart home, smart transportation, smart grid, smart logistics, smart agriculture, smart power, and smart industry.
The performance indexes of IOT are mainly the survival time of the network, the data transmission rate, transmission delay and so on. Based on these indexes, the thesis aims at making a summary of commonly used performance improvement methods of topology control and data fusion, and also making an analysis of the reasons why these methods can improve performance in actual application situations. Trough observing the result of the experiments in communication distance, simple handshake agreement, transmission power and communication channel, the existing agreement will be concluded. In addition, the experiment is largely completed on the MC13213 wireless communication module. The ZigBee technology applied in the experiment at the same time, analyzed the performance of the same node under different environmental conditions, on the Internet of things had the further understanding and communication performance.
