| In order to solve the problems of low data transmission quality and low network transmission bandwidth in the process of data
transmission of mobile Internet of things, a stable scheme of data transmission of mobile Internet of things based on node link evaluation
model is proposed. Considering the characteristics of node movement, a new node link evaluation model was designed to realize multidimensional evaluation of data transmission process. Then, according to the node link evaluation model, three indexes of data
transmission order, relay link control and transmission energy control were proposed. By matching the transmission power of nodes, a
link stability method based on the order degree of data transmission was designed, and the poisson distribution model was used to build a
node stability method based on the control degree of relay link, and by predicting the limited performance of nodes, a node failure state
transmission energy saving scheme based on the control degree of transmission energy was proposed, so that the data transmission
performance of the mobile Internet of things was optimized from node, link and energy, which can effectively improves the stability of the
network transmission. The simulation results show that compared with the data control synchronous transmission algorithm based on the
likelihood estimation compensation mechanism and LTE-5G data transmission algorithm based on the pre transmit precision improvement
mechanism, this algorithm has lower congestion level and node limited probability, and higher network transmission bandwidth. |
