Protocol selection criteria (bandwidth, power, latency) in IOT Protocols - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does bandwidth mean in the context of IoT protocols?

Bandwidth is the amount of data that can be sent over a network in a certain time, usually measured in bits per second (bps).

beginner

Why is power consumption important when choosing an IoT protocol?

Power consumption matters because many IoT devices run on batteries and need to last a long time without charging.

beginner

What is latency in IoT communication?

Latency is the delay between sending a message and receiving a response. Lower latency means faster communication.

intermediate

How does high bandwidth affect IoT device communication?

High bandwidth allows sending more data quickly, which is good for devices that need to transfer large amounts of information.

intermediate

What trade-offs might exist between power consumption and latency in IoT protocols?

Lower latency often requires more power, so devices must balance fast responses with battery life.

Which factor is most important for battery-powered IoT sensors?

A Low power consumption

B High bandwidth

C High latency

D Complex encryption

Battery-powered sensors need to use as little power as possible to last longer.

What does low latency in an IoT protocol mean?

A Long battery life

B Large data capacity

C Fast message delivery

D High power use

Low latency means messages travel quickly between devices.

If an IoT device sends large files, which protocol feature is most critical?

A Low power

B High bandwidth

C High latency

D Short range

High bandwidth allows sending large files faster.

What is a common trade-off when choosing IoT protocols?

A Color vs size

B Range vs color

C Speed vs weight

D Power vs latency

Often, faster communication uses more power, so devices balance these.

Which protocol feature helps extend battery life in IoT devices?

A Low power consumption

B High latency

C High bandwidth

D Complex setup

Using less power helps devices run longer on batteries.

Explain how bandwidth, power consumption, and latency influence the choice of an IoT protocol.

Think about what each term means and why it matters for small devices.

Describe a scenario where low latency is more important than low power consumption in IoT.

Imagine a device that must react instantly, like a safety alarm.
