Answer:
The most relevant option regarding the role of communication protocols in IoT is Mac layer issue.
Option (C) is true.
Step-by-step explanation:
The MAC (Medium Access Control) layer is a crucial component in communication networks, particularly in wireless communication where multiple devices share the same communication medium.
In the context of IoT (Internet of Things), which involves a vast number of interconnected devices, the role of communication protocols at the MAC layer is significant.
Here's an explanation of how the MAC layer and communication protocols contribute to the functionality of IoT:
Channel Access:
The MAC layer is responsible for managing how devices access the communication channel. In a network with numerous IoT devices, efficient channel access is crucial to avoid conflicts and ensure that multiple devices can communicate without interference.
Collision Avoidance:
In wireless networks, there is a risk of collisions when multiple devices attempt to transmit data simultaneously.
The MAC layer implements protocols and mechanisms to detect and avoid collisions, ensuring reliable and efficient communication.
Synchronization:
Devices in an IoT network need to be synchronized to ensure that they are transmitting and receiving data at the right times.
The MAC layer addresses synchronization issues, facilitating coordinated communication among devices.
Addressing:
The MAC layer helps in addressing devices uniquely within the network. Each device is assigned a MAC address, allowing for proper identification and routing of data.
Power Management:
Communication protocols at the MAC layer may include power management mechanisms to optimize energy consumption in IoT devices.
This is crucial for devices with limited power resources, helping to extend battery life and improve overall energy efficiency.
Thus, Option (C) is true.
