doi:10.11959/j.issn.1000-0801.2017333

Abstract

Abstract:

The internet of things (IoT) is the network of physical devices,vehicles,home appliances and other items embedded with electronics,software,sensors,actuators and network connectivity which enable these objects to connect and exchange data.Every sensor node is a source of information.In the offered method,telecom network operators could analyze the network data and discover the abnormal situation of the IoT terminals,so as to ensure the normal use of the IoT terminals.A network behavior tag for the IoT terminals by analyzing the network data in the telecom network,and a real-time monitoring method for the IoT terminal network behavior were described.And take the wearable industry application for example,the analysis process of the internet of things network behavior was described.

Key words: internet of things, network data, network behavior monitoring

行业类别	网络行为特征
可穿戴	可穿戴终端的上网时间和位置不固定，根据个人行为的不同而不同；可穿戴终端的上下行流量并不大，不超过10 Mbit/s的数据流量，数据波动比较大；如果终端不活跃，只有下行不到1 kbit/s的数据流量
智能抄表	智能抄表终端长时间在线，终端位置固定，上行流量（120~200 kbit/s）大于下行流量（70~90 kbit/s），终端持续保持活跃，数据传输比较稳定
车载Wi-Fi	车载Wi-Fi终端位置可以移动，终端持续在线，数据传输时间通常从上午6:00—8:00左右开始，到晚上22:00—23:00结束。上行流量小于下行流量
智能家居	智能家居终端位置固定，通常是白天9:00开始，晚上23:00或第二天0:00—2:00结束，或者是一整天持续数据传输。
	数据传输量保持稳定，大小一致。数据上下行流量都较大
车联网	车联网终端可以移动，终端持续在线，上网时间和位置并不固定，根据个人行为的不同而不同，车联网终端的上下行流量并不大，但是数据波动比较大
金融POS	金融POS终端可以移动，终端持续在线，数据传输时间较短，上行数据流量大于下行数据流量，数据量小于100 kbit/s，数据量变化较大
智能监控	智能监控终端位置固定，终端持续在线，数据持续传输，数据流量并不大，上行数据流量（小于300 kbit/s）大于下行数据流量（小于250 kbit/s），但是发现有次凌晨0:00时，下行数据流量（2 Mbit/s左右）大于上行数据流量（140 kbit/s）。会在凌晨0:00—2:00左右出现下行数据流量大于上行数据流量的情况
税控机	税控机终端位置固定，工作时间非常有规律，在工作日（9:00—16:00左右）终端处于在线状态，上行数据流量（小于10 Mbit/s）小于下行数据流量（最大可以到51 Mbit/s左右）
