Which clustering technique is commonly used in Wireless Sensor Networks (WSNs) to elect cluster heads and save energy?
LEACH is a classic distributed clustering protocol in WSNs that randomly rotates cluster head responsibilities to evenly distribute energy consumption.
What is 'Digital Twin' technology in Industrial IoT (IIoT)?
A Digital Twin is a dynamic computational model fed by real-time IoT sensor telemetry to simulate performance, predict maintenance, and optimize operations.
What protocol is widely used for interoperability between industrial automation devices and cloud enterprise software in Industry 4.0?
OPC UA (IEC 62541) is a cross-platform, service-oriented architecture protocol for industrial machine-to-machine communication.
In IoT privacy protection, what does 'Data Anonymization' involve?
Data anonymization strips sensitive PII (like user names, location coordinates) to comply with privacy frameworks like GDPR.
What is 'Time-Sensitive Networking' (TSN) in IIoT applications?
TSN extends standard Ethernet to guarantee low packet delay and bounded latency required for industrial control loops.
