摘　　要：节点连通性影响传输链路的分簇效果,会对链路负载均衡控制造成干扰,导致链路传输丢包率升高。为此,提出一种基于节点连通性的物联网链路传输负载均衡控制方法。根据物联网链路的传输原理,采用有向网络冲突图的形式建立链路信道传输模型,分别获取每条链路的传输时延和可用带宽,感知链路负载特征。根据链路节点直接连通概率的计算结果生成连通性随机图,对物联网链路节点进行分簇处理,并定义链路传输负载均衡控制区间,结合连通性和距离信息,在同一个簇内确定最优的负载转移节点,结合模糊PID控制原理生成负载均衡控制方案。实验结果表明,此链路传输负载均衡控制方法可以有效降低丢包率,符合负载传输要求。The node connectivity affects the clustering effect of the transmission link,and interferes with the link load balancing control,resulting in increased packet loss rate in link transmission.Therefore,a node connectivity-based link transmission load balancing control method of Internet of Things is proposed.Firstly,according to the link transmission principle of the Internet of Things,a link channel transmission model is established in the form of directed network conflict graph.Then,the transmission delay and available bandwidth of each link are obtained respectively,and the link load characteristics are sensed.Finally,according to the calculation results of the direct connectivity probability of the link nodes,a connectivity random graph is generated to cluster the IoT link nodes.Combining the connectivity and distance information,the optimal load transfer node is determined in the same cluster,and the fuzzy PID control principle is used to generate the load balancing control scheme.The experimental results show that this link transmission load balancing control method can effectively reduce the packet loss rate,which meets the load transmission requirements.
