Protocol selection criteria (bandwidth, power, latency) in IOT Protocols - Mini Project: Build & Apply

Protocol Selection Criteria: Bandwidth, Power, and Latency

📖 Scenario: You are working on a small IoT device project. You need to choose the best communication protocol based on three important factors: bandwidth, power consumption, and latency. Each protocol has different values for these factors.Imagine you have a list of protocols with their bandwidth (in kbps), power consumption (in mW), and latency (in ms). Your task is to filter and select protocols that meet certain criteria.

🎯 Goal: Build a simple program that stores protocol data, sets selection criteria, filters protocols based on these criteria, and then displays the selected protocols.

📋 What You'll Learn

Create a dictionary named protocols with exact entries for three protocols and their bandwidth, power, and latency values.

Create three variables named max_bandwidth, max_power, and max_latency with exact integer values for selection criteria.

Use a dictionary comprehension named selected_protocols to filter protocols that have bandwidth less than or equal to max_bandwidth, power less than or equal to max_power, and latency less than or equal to max_latency.

Print the selected_protocols dictionary.

💡 Why This Matters

🌍 Real World

IoT devices often need to choose communication protocols that balance speed, power use, and delay to work well in their environment.

💼 Career

Understanding how to filter and select protocols based on technical criteria is important for IoT engineers and DevOps professionals managing connected devices.

1

Create the protocols dictionary

Create a dictionary called protocols with these exact entries: 'Zigbee': {'bandwidth': 250, 'power': 60, 'latency': 15}, 'Bluetooth': {'bandwidth': 1000, 'power': 100, 'latency': 30}, 'LoRa': {'bandwidth': 50, 'power': 10, 'latency': 300}.

IOT Protocols

# Create the protocols dictionary with exact values
# Your code here

Need a hint?

Use a dictionary with protocol names as keys and another dictionary as values holding bandwidth, power, and latency.

2

Set selection criteria variables

Create three variables called max_bandwidth, max_power, and max_latency with values 300, 70, and 50 respectively.

IOT Protocols

protocols = {
    'Zigbee': {'bandwidth': 250, 'power': 60, 'latency': 15},
    'Bluetooth': {'bandwidth': 1000, 'power': 100, 'latency': 30},
    'LoRa': {'bandwidth': 50, 'power': 10, 'latency': 300}
}
# Create max_bandwidth, max_power, and max_latency variables with values 300, 70, and 50
# Your code here

Need a hint?

Assign the exact integer values to each variable as given.

3

Filter protocols using dictionary comprehension

Create a dictionary comprehension called selected_protocols that includes only protocols from protocols where bandwidth is less than or equal to max_bandwidth, power is less than or equal to max_power, and latency is less than or equal to max_latency.

IOT Protocols

protocols = {
    'Zigbee': {'bandwidth': 250, 'power': 60, 'latency': 15},
    'Bluetooth': {'bandwidth': 1000, 'power': 100, 'latency': 30},
    'LoRa': {'bandwidth': 50, 'power': 10, 'latency': 300}
}
max_bandwidth = 300
max_power = 70
max_latency = 50
# Create selected_protocols dictionary comprehension filtering protocols by criteria
# Your code here

Need a hint?

Use a dictionary comprehension with for name, specs in protocols.items() and filter with if conditions.

4

Print the selected protocols

Write a print statement to display the selected_protocols dictionary.

IOT Protocols

protocols = {
    'Zigbee': {'bandwidth': 250, 'power': 60, 'latency': 15},
    'Bluetooth': {'bandwidth': 1000, 'power': 100, 'latency': 30},
    'LoRa': {'bandwidth': 50, 'power': 10, 'latency': 300}
}
max_bandwidth = 300
max_power = 70
max_latency = 50
selected_protocols = {name: specs for name, specs in protocols.items() if specs['bandwidth'] <= max_bandwidth and specs['power'] <= max_power and specs['latency'] <= max_latency}
# Print the selected_protocols dictionary
# Your code here

Need a hint?

Use print(selected_protocols) to show the filtered dictionary.
