摘　　要：针对物联网节点传输过程中存在的数据拥塞控制能力不高及带宽受限等,采用了基于层次冗余机制的物联网数据超宽带传输算法。通过拆解核心控制节点内数据报文所包涵的分层信息,解析坐标并按地理位置远近对数据报文执行重传输机制。设计核心控制-传输亲缘关系的中继节点筛选方法,将具有相似数据分组特征的节点划入中继节点聚类,实现中继节点的多态化筛选。计算节点与链路传输成功概率,并建立拷贝拆分机制,按拆分后的分组逐片校验链路,优选具有最高成功概率的链路进行数据传输,并按网络时延动态切换备用传输链路。通过仿真实验得到如下结论:所提算法的数据报文遗失概率在10%以下,节点传输平均时延较低,网络传输带宽也得到较高幅度的提升。A hierarchical redundancy mechanism based ultra wideband transmission algorithm for IoT data is adopted to address the shortcomings of low data congestion control capability and bandwidth limitations in the transmission process of high-density IoT nodes.By disassembling the hierarchical information contained in the data packets within the core control nodes,analyzing coordinates,and executing a retransmission mechanism for the data packets based on geographical location.A relay node screening method for core control transmission affinity was designed to categorized nodes with similar data grouping characteristics into relay node clustering,improving the clustering degree of relay nodes.Subsequently,the success probability of node and link transmission is defined and accurately calculated based on node penetration.A copy splitting mechanism is established by verifying the success probability of data sharding transmission.The link with the highest success probability is selected for data transmission,and the backup transmission link is dynamically switched based on network latency.Through simulation experiments,the following conclusion can be drawn:the proposed algorithm can achieve a data packet loss probability of less than 10%,lower average node transmission delay,and significantly improve network transmission bandwidth.
