With the increasing number of sensors in the Internet of Things (IoT), network nodes are prone to load imbalance, which seriously affects the reliability and scalability of the IoT. In this paper, a method of load balancing is proposed to reduce the pressure of switches in IoT and improve the efficiency of switch. The method is based on software defined network (SDN) technology using dynamic traffic scheduling of server cluster (DTSSC) model. It obtains the traffic and load matrices for each server and achieves load balancing on each of them. This method has high efficiency and low overhead and is easy to deploy. The validity of this method is verified through experiments; ie, the load ratio of each server is balanced.

基于流量矩阵的物联网安全调度方法研究

随着物联网（IoT）中传感器数量的增加，网络节点容易出现负载失衡，这严重影响了IoT的可靠性和可扩展性。本文提出了一种负载均衡的方法，以减轻物联网中交换机的压力并提高交换机的效率。该方法基于软件定义网络（SDN）技术，该技术使用服务器群集的动态流量调度（DTSSC）模型。它获取每个服务器的流量和负载矩阵，并在每个服务器上实现负载平衡。该方法效率高，开销低，易于部署。通过实验验证了该方法的有效性。即，每个服务器的负载率是平衡的。
