"With the exploitation of myriads of low-cost reflecting/refracting elements, reconfigurable intelligent surfaces (RISs) [8] and stacked intelligent metasurfaces (SIMs) [9] can adaptively ameliorate the propagation channel between transmitters and receivers by beneficially designing their phase shifts and/or amplification."
"By utilizing state-of-the-art smart technologies like intelligent surfaces [3], fluid antenna systems (FAS) [4], and holographic MIMO [5], combined with innovative cell-free and mobile air-ground networks [6], the propagation environments can be beneficially managed with increased flexibility and efficiency."
"For complementing conventional terrestrial cellular networks, BSs or relays may also be installed on unmanned aerial/ground/underwater vehicles to provide enhanced coverage."
"In FAS [4], the positions of antennas at transmitters and/or receivers can be dynamically changed to obtain improved channel conditions, e.g., enhancing the channel gain and reducing potential interference."
"Effectively combining these techniques can proactively adapt to wireless propagation environments by leveraging shared features for efficient management in terms of time, energy, cost."

How can AI assist in optimizing smart environments for ISAC applications?

Artificial Intelligence (AI) plays a crucial role in optimizing smart environments for Integrated Sensing and Communication (ISAC) applications. AI-based approaches enable real-time adaptation of smart environments by predicting future network states using recent propagation data. By leveraging AI, the complexity of designing holistic smart environments across various components like UAV trajectories, Reconfigurable Intelligent Surfaces (RIS), and Fluid Antenna Systems (FAS) can be reduced. AI solutions facilitate efficient resource allocation by evaluating only a fraction of the combined search space, thus enhancing the performance of ISAC systems.

What are the security implications of integrating smart environments with ISAC technology?

Integrating smart environments with ISAC technology introduces unique security challenges due to shared spectrum use and wireless transmission's broadcast nature. The collaborative nature of these technologies may lead to potential vulnerabilities if not adequately secured. Security concerns include unauthorized access to sensing information, interception of target locations, and eavesdropping on communication channels. Securing ISAC services requires addressing physical layer security issues since traditional data-level security measures may not suffice in this context.

How can vehicular cooperation schemes benefit from smart propagation engineering?

Vehicular cooperation schemes stand to benefit significantly from incorporating smart propagation engineering techniques. By harnessing similarities in vehicle mobility characteristics within specific formations such as platoons, control overhead can be minimized through cooperative designs tailored for vehicular networks. Smart propagation engineering allows vehicles to collaboratively gather information over wider fields of view, enhancing situational awareness for transportation purposes. Additionally, onboard sensors on vehicles provide valuable environmental data that can inform intelligent decision-making processes within the vehicular network setup.
