Dataset Modeling for Data-Driven AI-Based Personalized Wireless Networks

Abstract

Current wireless networks are over-provisioned in order to maintain an average acceptable user experience for most users on the network. Over-provisioned networks suffer from several issues, however, including network inefficiency and the inability to maintain a certain user satisfaction level for all users. Data-driven wireless network personalization is proposed as a dynamic context-aware approach to maintaining the targeted personalized satisfaction levels with minimum resources. Wireless network personalization has two key enablers: measuring and predicting user satisfaction in real-time, and datasets that have both context and user satisfaction information. In this paper, we first present the Zone of Tolerance (ZoT) concept, which is proposed for modeling the relationship between context, service performance, and user satisfaction. Then, since datasets for user behavior and their corresponding satisfaction levels do not exist due to privacy and confidentiality concerns, we propose a process based on the ZoT model for synthesizing a context-based dataset along with its corresponding user satisfaction values. Finally, an exemplary user satisfaction prediction experiment is conducted with the generated dataset using several Machine Learning (ML) algorithms.
