To solve the bottleneck problems in the deployment of mobile internet of things,such as low reliability and poor quantification,a bottleneck analysis of mobile internet of things performance based on data stabilization scheme was proposed.Based on the drift characteristics of mobile internet of things nodes,a data loss model was designed depending on data path loss,channel fading loss and point transmission fading loss to evaluate the bottleneck factors in the data transmission process of mobile internet of things.Relying on the data loss model proposed,according to the dimensions of node energy limitation,transmission node stability and network burst stability,a mathematical analytical form of evaluation equation was constructed to analyze the performance of mobile internet of things.The network performance of the proposed data loss model was tested.The results show that the proposed scheme has strong ability to analyze the bottleneck of mobile internet of things,which can effectively improve the data transmission performance and congestion control performance of common schemes.
