A Reinforcement Learning-Based Configuring Approach in Next-Generation Wireless Networks Using Software-Defined Metasurface
Table 1
Summary of the main adaptive configuration approaches for PWE tiles.
| Reference | Approach | Discussion |
| Liaskos et al. [16] | Genetic algorithm (GA) | This approach cannot adaptively reconfigure the tiles functionality as soon as the environment changes. | Liaskos et al. [9] | Neural network | This approach considered a problem with only one user. | Liaskos et al. [17] | Graph model | This approach is time-consuming to reconfigure the states of the tiles when the environment changes. | This work | RL | This approach can adaptively reconfigure the states of the tiles when the environment changes in presence of multiple users. |
