摘要
准确判别物联网数据转储节点的阻塞状态,可提高物联网数据转储率,提出基于改进阻塞判别算法的物联网数据转储方法,判断物联网数据转储节点是否存在阻塞状态,若转储节点不存在阻塞状态,便由基于超宽带集中管控机制的物联网数据转储效果优化算法,通过转储区域分割、转储区域固定、转储链路稳定三步骤,优化物联网数据转储节点在接收物联网数据时的接收链路稳定性与传输性能,实现物联网数据稳定高效转储。仿真结果显示:所提方法在转储物联网数据时,对转储节点状态判断精度高,转储率、信道容量高于对比方法;节点时延、传输抖动率、丢包率低于对比方法,转储性能显著。
It is necessary to judge the blocking state of data dump nodes accurately to improve the data dump rate of Internet of things.Therefore,this paper proposes the Internet of Things data dump method based on the improved blocking discrimination algorithm.Firstly,the blocking state of the data dump node in the Internet of things was determined.When the dump node was unblocked,the algorithm was optimized by the data dump effect of the Internet of things based on the ultra-wideband centralized control mechanism.Then,the receiving link stability and transmission performance of the Internet of things data dump node were optimized by dividing,fixing and stabilizing the dump area.Finally,the stable and efficient data dump of Internet of things was realized.The simulation results show that this method is superior to the traditional method in judging the state of dump node,dump rate and channel capacity,and the node delay,transmission jitter rate and packet loss rate are also lower than the traditional method.
