增强学习机制下的工业物联网可信信息覆盖协同控制策略研究

Coverage is one of the most important criteria which can measure the quality of service and performance of the Industrial Internet of Things (IIoT), therefore, the coverage control is the crucial issue in the research topics of IIoT. There are several typical shortcomings in the existing related coverage control theories and methods. For example, the widely used disk coverage model is too idealistic to be applied in practical scenarios. Most of the current coverage strategies ignore the heterogeneity and spatial correlation of the monitored environmental parameters and haven’t considered the unknown sensing region and network environment. In order to overcome the existing drawbacks in the related works, considering the requirements of the industrial monitoring application, this project focuses on the coverage control problem in the industrial internet of things based on the novel confident information coverage model and reinforcement learning. The major investigations of this project can be summarized as follows: (1)We study how to energy efficiently deploy a number of nodes in the industrial region of interest by devising penalty and reward mechanisms based on the irregular rule cell learning automata model to satisfy the confident information coverage; (2) We propose some confident information coverage node scheduling protocols based on the dynamic irregular cell learning automata model to prolong the network lifetime; (3) We will evaluate and cross-verify the performance of the proposed models and algorithms by experimental simulations and a practical network prototype. The proposed theories and methods in this project can dramatically save network deployment cost, prolong network lifetime, improve network coverage and quality of service. The research of this project will remarkably extend the current coverage control theory and methodology framework in industrial internet of things, which can effectively guide the IIoT-based practical industrial environment monitoring applications.
