ZigBee applications are mainly designed for:
High-speed multimedia
Long-distance communication
Low-power and low-data-rate applications
Satellite communication
Why does ZigBee use IEEE 802.15.4 as its base standard?
It supports high data rates
It provides low power and low cost communication
It supports long-range communication
It provides wired connectivity
What is the role of the ZigBee Coordinator in the network?
Only transmits data
Initiates and manages the network
Acts as an end device
Provides internet access
How does a ZigBee Router differ from an End Device?
Router cannot forward packets
End device can route packets
Router forwards packets while end device does not
Both perform the same function
Why is the Network layer important in ZigBee?
It controls signal modulation
It manages routing and addressing
It encrypts application data only
It handles user interfaces
Simple Tree Routing is preferred because it:
Requires complex route discovery
Uses minimum memory and processing
Provides shortest paths always
Works only in mesh networks
Why is ZAODV used in ZigBee mesh networks?
It reduces device cost
It supports dynamic route discovery
It eliminates routing overhead
It increases transmission power
What is the main function of the APS layer?
Channel access control
Device association
Data delivery between applications
Signal encoding
APS layer enhances security by:
Controlling frequency bands
Managing application-level keys
Assigning IP addresses
Performing routing
ZigBee is best suited for which application?
Video streaming
Smart home automation
Online gaming
Cloud computing
Tree routing may be inefficient when:
Network size is small
Network is static
Traffic pattern changes frequently
Nodes are fixed
