ESP32 Virtual Network Test Results

100 simulated ESP32 nodes across 5 Munich districts, running the actual firmware routing logic. Mixed LoRa ranges: 20% rooftop nodes (3km) + 80% handheld (1.5km).

How This Differs from the Python Simulator

Python Simulator (22 Scenarios)

Abstract routing algorithms — no wire protocol
Perfect neighbor knowledge (global adjacency matrix)
Link quality as a simple probability (0-1)
No OGM discovery — topology known upfront
No packet serialization — function calls
Hundreds to thousands of nodes
Useful for: algorithm comparison at scale

ESP32 Virtual Network (This Test)

Actual firmware C logic reimplemented in Python
OGM-based neighbor discovery — nodes learn topology over 3 rounds
RSSI-based link quality from log-distance path loss model
Wire protocol packets — 22-byte headers, serialized/deserialized
Probabilistic reception — packets can fail based on distance
Geohash clustering — same algorithm as ESP32 firmware
Useful for: firmware verification before hardware deployment

Key difference: The Python simulator tests the algorithm concept (does System 5 routing work better than flooding?). The ESP32 virtual network tests the firmware implementation (does the actual code that runs on hardware produce correct results?). Both agree: System 5 saves ~89% of transmissions with 100% delivery on this 10-node network.
