Review Questions

• How does improving efficiency in IoT applications affect energy consumption?
  • Improving efficiency in IoT applications directly impacts energy consumption by minimizing unnecessary resource use. For example, devices that operate only when needed and intelligently manage their connectivity can drastically lower their power requirements. This not only leads to cost savings for users but also contributes to environmental sustainability by reducing the overall carbon footprint of technology.
• Discuss the relationship between latency and efficiency in IoT systems.
  • Latency is a critical factor that affects the efficiency of IoT systems since high latency can lead to delays in data processing and response times. Efficient systems aim to minimize latency to ensure that devices communicate quickly and reliably. By reducing delays, IoT applications can perform tasks in real time, enhancing user experience and operational effectiveness, especially in scenarios like autonomous vehicles or remote healthcare monitoring.
• Evaluate how scalability plays a role in maintaining efficiency as IoT applications expand.
  • As IoT applications grow, maintaining efficiency becomes challenging without scalable solutions. Scalability ensures that systems can handle increased loads without compromising performance. Efficiently designed scalable architectures allow for the addition of new devices and functionalities while maintaining optimal resource utilization. This adaptability is crucial for evolving environments such as smart cities, where increased sensor deployment must not degrade system responsiveness or increase operational costs.
