Reconfigurable intelligent surface (RIS)-inspired splitfed learning for over-the-air

The scientific community is transitioning toward sixth-generation (6G) technology, with a focus on meeting the escalating requirement for secure wireless connectivity amidst the surge in wireless data traffic and the need for low-latency communication. The notion of reconfigurable intelligent surfaces (RIS) emerges as a solution to mitigate security vulnerabilities by intelligently manipulating wireless channel conditions, thus presenting a promising avenue for 6G wireless communication. Delving into the applications of RIS within the context of 6G, various configurations of RIS-assisted wireless systems are scrutinized, covering diverse scenarios, system and fading models, as well as performance metrics and objectives, in a comprehensive and methodical manner.
