Summary
This study introduces a new method using conditional-super-resolution GAN (CSR-GAN) to generate mobile traffic data, significantly reducing storage costs by up to 45% while maintaining high accuracy.
Area of Science:
- Data Science
- Computer Science
- Network Engineering
Background:
- Mobile traffic data analysis is crucial for urban planning, but escalating data volumes increase storage costs.
- Existing methods using generative adversarial networks (GANs) reduce data but still require storing coarse-grained representations.
- This necessitates more efficient data generation and storage solutions for mobile traffic data.
Purpose of the Study:
- To propose a novel scheme for generating mobile traffic data using conditional-super-resolution GAN (CSR-GAN).
- To eliminate the need for a coarse-grained data representation process, thereby reducing storage requirements.
- To evaluate the accuracy and storage efficiency of the proposed CSR-GAN method compared to traditional approaches.
Main Methods:
- Implementation of a conditional-super-resolution GAN (CSR-GAN) model for mobile traffic data generation.
- Utilizing real-world mobile traffic datasets for experimental validation.
- Comparative analysis of storage costs and data generation accuracy against existing methods.
- Investigating the impact of CSR-GAN architecture variations on performance and storage needs.
Main Results:
- The proposed CSR-GAN scheme reduces storage costs by up to 45% compared to traditional methods.
- The generated mobile traffic data achieves an accuracy of 94% in reconstructing original data.
- Experiments revealed an optimal relationship between traffic data volume and CSR-GAN model size.
Conclusions:
- CSR-GAN offers a significant reduction in storage costs for mobile traffic data management.
- The method effectively generates high-accuracy mobile traffic data without intermediate coarse-grained representations.
- Findings suggest that CSR-GAN is a viable and efficient solution for large-scale mobile traffic data analysis and planning.
