## ✨ Core Features

- **High-Performance Event-Driven Simulation Core:** Optimized event-driven simulation engine achieving sub-O(n log n) computational complexity for critical operations, enabling efficient simulation of large-scale scenarios.

- **Workflow-Based Task Composition Framework:** Flexible and modular workflow-driven task model that explicitly captures task dependencies, resource constraints, and collaborative interactions among heterogeneous nodes.

- **Standards-Compliant Realistic Modeling:** Comprehensive models grounded in established standards, including 3GPP-compliant communication channel models, empirically validated energy consumption profiles, and physics-based mobility patterns.

- **Agent-Centric Autonomy:** Agents (like UAVs) as primary actors with internal state, capable of autonomous decision-making based on their state, assigned workflows, and environmental perception.

- **Component-Based Capabilities:** Clear separation of concerns with components encapsulating specific functionalities (mobility, computation, sensing) and managing task execution environments.

- **Trigger-Based Reactivity:** Flexible mechanism for reacting to various conditions (events, state changes, time), driving workflow state machine transitions and enabling automated responses.

- **Managed Resources:** Simulation resources (landing spots, CPU, airspace, spectrum) managed by dedicated manager classes handling registration, allocation, contention, and dynamic attribute changes.

- **Real-time Visualization:** Integrated frontend interface supporting real-time monitoring and data analysis.

- **LLM Integration:** Support for task planning and decision-making through large language models.

## 🏗️ System Architecture

AirFogSim is built around an event-driven Agent-Based Modeling (ABM) architecture that enables efficient simulation of complex interactions between heterogeneous agents. The platform extends the SimPy discrete-event simulation library, providing specialized components for UAV-integrated fog computing scenarios.

### Core Components

- **🤖 Agents**: Autonomous entities (UAVs, ground stations) with decision-making capabilities
- **🔧 Components**: Modular capabilities (mobility, computation, sensing) that agents can use
- **📋 Tasks**: Specific actions that agents perform through their components
- **🔄 Workflows**: Higher-level goals that coordinate multiple tasks
- **⚡ Triggers**: Event-driven conditions that drive workflow transitions
- **📊 Resources**: Shared simulation resources (airspace, spectrum, landing spots)
- **🎯 Managers**: Centralized management of resources and system services

For detailed architecture documentation, see [System Architecture Guide](src/airfogsim/docs/en/architecture.md).

### Visualization System

AirFogSim includes an integrated visualization system for real-time monitoring:

- **📊 Dashboard**: Simulation status and agent monitoring
- **🗺️ UAV Tracking**: Real-time position and trajectory visualization
- **⚙️ Workflow Monitor**: Configuration and execution tracking
- **📈 Analytics**: Resource usage and performance metrics

## 📝 Usage Examples

### Basic Simulation Example

```python
from airfogsim.core.environment import Environment
from airfogsim.agent import DroneAgent
from airfogsim.component import MoveToComponent, ChargingComponent
from airfogsim.workflow.inspection import create_inspection_workflow
from airfogsim.helper import check_all_classes, find_compatible_components

# Create environment
env = Environment()

# Check system classes
check_all_classes(env)

# Create drone agent
drone = env.create_agent(
    DroneAgent,
    "drone1",
    initial_position=(10, 10, 0),
    initial_battery=100
)

# Find suitable components
find_compatible_components(env, drone, ['speed'])

# Add components
move_component = MoveToComponent(env, drone)
charging_component = ChargingComponent(env, drone)
drone.add_component(move_component)
drone.add_component(charging_component)

# Create inspection workflow
waypoints = [
    (10, 10, 100),    # Take off
    (400, 400, 150),  # Midpoint
    (800, 800, 150),  # Destination
    (800, 800, 0),    # Land
    (800, 800, 100),  # Take off for return
    (10, 10, 0)       # Return to start
]
workflow = create_inspection_workflow(env, drone, waypoints)

# Start workflow
workflow.start()

# Run simulation
env.run(until=1000)
