摘　　要：物联网中存在不同处理速率的终端设备和不同类型的通信网络,传输的数据大多对时延和带宽具有一定要求。如何保障物联网中各通信设备之间进行有效的数据传输,使得各链路上的数据流量符合要求,防止数据溢出,在物联网中进行流量控制具有十分重要的意义。文中结合停止等待协议、自动请求重传(Automatic Repeat request)ARQ协议和滑动窗口协议,提出了在物联网中应用流量控制的方法和措施。有利于提高和改善物联网中数据传输的效率。In the Internet of things, there are terminal devices with different processing speed and different types of communication networks. Most of the data transmission has a certain requirement for delay and bandwidth. Flow control in the Internet of things is very important,which can guarantee the efficient data transmission of different communication devices and make the data flow on each link to meet the requirements and avoid data overflow. In this paper,the methods of flow control in the Internet of things are put forward, which combined with the stop and wait protocol, the automatic repeat request （ARQ ） protocol and the sliding window protocol. It is advantageous to improve the efficiency of data transmission in the Internet of things.
