摘　　要：为解决物联网部署过程中存在的链路稳定性能较差、骨干链路形成困难、节点传输受限等不足,提出了一种基于流量阀损耗均衡机制的物联网链路稳定算法。首先,基于广播反馈机制实现sink节点与簇头节点之间的链路信息交互,设计了基于节点均衡机制的链路稳定方法,通过广播数据报文及时提醒节点过载现象,降低簇头节点的分流压力。随后,基于预设阀值并结合数据反馈方案,构建了基于流量阀机制的带宽控制方法,采取流量均衡化方式定期关闭过载节点,以提高网络数据传输能力,改善链路抖动现象。In order to solve the problems in the deployment of the Internet of Things,such as poor link stability,difficulties in backbone link formation and limited node transmission,a link stability algorithm based on the flow valve loss balancing mechanism is proposed.First of all,the algorithm realizes the link in⁃formation interaction between sink node and cluster head node based on broadcast feedback mechanism,and designs a link stability method based on node balance mechanism,which timely alerts the node overload phe⁃nomenon through broadcast data packets to reduce the diversion pressure of cluster head nodes.Then,based on the preset threshold and combined with the data feedback scheme,the algorithm constructs a bandwidth control method based on the flow valve mechanism,and takes the flow equalization method to shut down the overload nodes periodically to improve the network data transmission capacity and improve the link jitter.Simulation results show that the proposed algorithm can significantly reduce the frequency of link jitter in the Internet of Things and has the characteristics of strong node transmission capacity.
