CupCarbon Klaines: A Simulator for Smart City, IoT and
Wireless Sensor Networks with Agentic AI

The CupCarbon Project — cupcarbon.com

Version Klaines 8.0, 2026 — Free software (GNU GPL)

Abstract — CupCarbon is a Smart City and Internet of Things Wireless Sensor Network (SCI-WSN) simulator. Networks are designed directly on an OpenStreetMap city map and simulated with a discrete-event engine, taking into account radio propagation, interference, mobility, energy consumption and the urban environment (buildings). The Klaines generation introduces agentic artificial intelligence: a visual, n8n-style workflow editor in which IoT nodes exchange data with AI agents connected to real large language models (Anthropic Claude, OpenAI), together with Python-programmable nodes (cup_* functions), MQTT remote control from any browser, and native packages for every platform. CupCarbon is used for research, engineering and education.

2. Simulation features

Discrete-event WSN engine

Faithful simulation of sensor networks: radio communication (ZigBee, WiFi, LoRa), energy and battery models, sensor events, fault injection and result logging.

City-scale environment

Design on real OpenStreetMap maps; buildings are imported from Overpass and used in the radio visibility model, which recomputes ranges live while nodes move.

Mobility

GPS routes, speeds and mobile nodes; trajectories designed on the map and followed during the simulation.

Python-programmable nodes

Each IoT node runs a real external Python script through the cup_* API (29 functions: mobility, sensing, messaging, display) with a syntax-highlighted editor and per-function help.

3. Agentic AI workflows

The Klaines generation embeds a visual workflow editor inspired by n8n. Workflows are built from nodes (triggers, logic, MQTT, AI) connected on a canvas, run continuously and independently from the simulation, and exchange messages with the sensor nodes through cup_toagent() / cup_fromagent(). The AI Agent node connects to Anthropic Claude or OpenAI (user-provided API key, with an offline rule-based fallback and conversation memory), enabling chatbots and autonomous decision loops that drive the network. Workflows use the n8n item data model with JavaScript {{ $json }} expressions evaluated in a fully sandboxed engine. Read the Agentic AI documentation →

4. Remote control and web tools

CupCarbon can be driven from any browser through MQTT with secure per-session topics: a web console (all simulator commands), CupCarbon Studio (console + workflow exchange with visual preview), a full web workflow editor, and the command reference with three examples per command.

5. Download and installation

One package per platform; each contains the application, its launcher and the runtime resources. Install Java 17+ (adoptium.net) and Python 3 (python.org), unzip, launch. The installation guide details every step, per platform.
