摘　　要：随着智能家居的迅猛发展,使其在高、中、低不同市场上都存在着很多竞争。Yun OS智能操作系统的推出也加快了智能家居行业的发展。Message Queuing Telemetry Transport(MQTT)协议是为大量计算能力有限,并且工作在低带宽、不可靠的网络的远程传感器和控制设备通信而设计的协议。由于开销小,适用小型传输,在智能家居中得到大量运用。通过对MQTT协议结构以及关键字段的研究,并从实际环境中抓取到的智能家居中Packet Capture(PCAP)包进行分析,提出一种改进型的消息过滤算法将MQTT协议中订阅的主题与智能家居品牌联系起来,实现识别智能家居设备厂商的目的。With the rapid development of the smart home,a lot of competitions exist in its various high,medium and low level markets.On the other hand,the launch of the YunOS smart operating system also speeds up the development of the smart home industry.The message queuing telemetry transport(MQTT)protocol is designed for communications between a great quantity of remote sensors and control equipments which have limited calculation capabilities and work on unreliable low-bandwidth networks.As the MQTT protocol has small overheads and is suitable for small transmissions,it is widely used in the smart home.An improved message filtering algorithm is proposed by studying the structure and key fields of the MQTT protocol,and analyzing the PCAP package grasped in real environments for the smart home,so as to associate the subscription topics of the MQTT protocol with the smart home brands,which can achieve the purpose of identifying the manufacturers of smart home equipments.
