What is a key characteristic of operational modes in CPS nodes?

A key characteristic of operational modes in Cyber-Physical Systems (CPS) nodes is that they influence energy consumption patterns. In CPS, each operational mode is typically designed to optimize the performance of various functions, and this often involves managing energy use. Different modes may prioritize factors such as data processing, communication, or standby, which leads to variations in energy consumption. For instance, a node may operate in a high-energy mode when actively sensing or transmitting data and switch to a low-energy mode when idle or in a monitoring state. This ability to manage energy consumption efficiently is crucial in CPS applications, where limited energy resources must be utilized effectively to maintain system functionality over time.

The focus on energy consumption aligns with the goals of sustainability and efficiency, especially in scenarios where nodes are battery-operated or need to operate for extended periods without recharging. Understanding this characteristic is vital for designing and optimizing energy management strategies in CPS nodes.
