import time
import random

def process_data_at_edge(data):
    # Simulate edge processing (faster)
    time.sleep(0.1)
    return f"Processed at edge: {data}"

def process_data_in_cloud(data):
    # Simulate cloud processing (slower due to network latency)
    time.sleep(1)
    return f"Processed in cloud: {data}"

def generate_sensor_data():
    return random.randint(1, 100)

# Simulate 10 data points
for _ in range(10):
    sensor_data = generate_sensor_data()
    
    start_time = time.time()
    edge_result = process_data_at_edge(sensor_data)
    edge_time = time.time() - start_time
    
    start_time = time.time()
    cloud_result = process_data_in_cloud(sensor_data)
    cloud_time = time.time() - start_time
    
    print(f"Edge processing time: {edge_time:.2f}s - {edge_result}")
    print(f"Cloud processing time: {cloud_time:.2f}s - {cloud_result}")
    print("---")

This script demonstrates the potential time savings of processing data at the edge compared to sending it to a centralized cloud for processing. In real-world scenarios, the difference in processing time can be even more significant, especially for time-sensitive applications.
