6LoWPAN Quiz

What does 6LoWPAN stand for?

• Bluetooth Low Energy Wireless Personal Area Network

• IPv6 over Low-Power Wireless Personal Area Network

• IPv4 over Low-Power Wireless Personal Area Network

• Internet Protocol over High-Power Ethernet Network

What is the purpose of IPv6 over Low-Power Wireless Personal Area Networks?

• To provide a more efficient and scalable communication protocol for low-power devices in IoT and smart home applications.

• To improve the taste of low-power devices

• To increase the speed of data transfer

• To reduce the number of available communication channels

What is the IEEE standard for low-rate wireless personal area networks?

• 802.22

• 802.15.4

• 802.11

• 802.16

What are the key features of IEEE 802.15.4?

• High power consumption, high data rate, high cost, and support for high complexity devices

• Medium power consumption, medium data rate, medium cost, and support for medium complexity devices

• No power consumption, no data rate, no cost, and no support for any devices

• Low power consumption, low data rate, low cost, and support for low complexity devices

What is mesh networking in the context of 6LoWPAN?

• A networking technique that relies on a single central node for all communication

• A networking technique that requires a physical connection between devices

• A networking technique where devices can communicate with each other through intermediate nodes, creating a self-healing and resilient network.

• A networking technique that only allows communication between devices within the same room

How does mesh networking help in improving network reliability?

• It provides multiple paths for data to travel, reducing the risk of single point of failure.

• It only allows data to travel through a single path, increasing the risk of single point of failure.

• It slows down the data transmission by creating unnecessary routes.

• It limits the number of devices that can connect to the network, reducing reliability.

What is header compression and why is it important in 6LoWPAN?

• It has no impact on the efficiency of IPv6 headers in low-power and lossy networks.

• It increases the overhead of IPv6 headers in low-power and lossy networks.

• It reduces the overhead of IPv6 headers in low-power and lossy networks.

• It only works for high-power and stable networks.

What are the benefits of using header compression in 6LoWPAN?

• Increased latency and slower data transmission

• Bandwidth saving and improved network efficiency

• Limited network coverage and connectivity issues

• Higher power consumption and reduced battery life

What are the layers in the 6LoWPAN protocol stack?

• Application, Presentation, Session, and Transport

• Physical, Link, Network, and Application

• Data, Transport, Session, and Presentation

• Network, Data Link, Transport, and Session

Explain the role of each layer in the 6LoWPAN protocol stack.

• The network layer is responsible for managing user authentication

• The physical layer is responsible for managing network security

• The physical layer is responsible for transmitting and receiving data over the physical medium, the link layer handles addressing and error detection, the network layer manages routing and addressing, and the transport layer ensures end-to-end communication and data integrity.

• The link layer handles data encryption and decryption
