## 🌟 Overview

The WIA-COMM-017 standard defines the comprehensive framework for mesh networking technologies, including self-healing topologies, multi-hop routing protocols, and decentralized network architectures. This standard covers WiFi mesh (802.11s), Bluetooth mesh, IoT mesh protocols (Thread/Zigbee), and LoRa mesh networks.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to enable resilient, scalable, and decentralized networking solutions that bring connectivity to underserved areas and enhance network reliability worldwide.

## 🎯 Key Features

- **Self-Healing Topology**: Automatic route reconfiguration on node failure
- **Multi-Hop Routing**: AODV, OLSR, BATMAN, and custom routing protocols
- **WiFi Mesh (802.11s)**: Standards-based wireless mesh networking
- **Bluetooth Mesh**: Low-power mesh for IoT and smart home
- **Thread/Zigbee Mesh**: IPv6-based IoT mesh networking
- **LoRa Mesh**: Long-range, low-power mesh networks
- **Decentralized Architecture**: No single point of failure
- **Node Discovery**: Automatic peer detection and pairing
- **Bandwidth Optimization**: Intelligent traffic routing
- **Latency Management**: QoS and priority routing

## 📊 Core Concepts

### 1. Mesh Topology

```
Node A ←→ Node B ←→ Node C
  ↕         ↕         ↕
Node D ←→ Node E ←→ Node F
  ↕         ↕         ↕
Node G ←→ Node H ←→ Node I
```

Each node can communicate with multiple neighbors, creating redundant paths for data transmission.

### 2. Routing Protocols

#### AODV (Ad hoc On-Demand Distance Vector)
- Reactive routing protocol
- Discovers routes only when needed
- Minimizes network traffic

#### OLSR (Optimized Link State Routing)
- Proactive routing protocol
- Maintains topology information
- Fast route computation

#### BATMAN (Better Approach To Mobile Ad-hoc Networking)
- Decentralized routing
- No global knowledge required
- Resilient to network changes

### 3. Network Types

| Type | Range | Bandwidth | Power | Use Cases |
|------|-------|-----------|-------|-----------|
| WiFi Mesh (802.11s) | 100-300m | 100+ Mbps | High | Home, Enterprise |
| Bluetooth Mesh | 10-50m | 1-2 Mbps | Low | IoT, Smart Home |
| Thread/Zigbee | 10-100m | 250 Kbps | Very Low | IoT Sensors |
| LoRa Mesh | 2-15km | 50 Kbps | Very Low | Rural, Agricultural |

## 🔧 Components

### TypeScript SDK

```typescript
import {
  MeshNetwork,
  createMeshNode,
  discoverPeers,
  routePacket
} from '@wia/comm-017';

// Create a mesh node
const node = createMeshNode({
  id: 'node-001',
  protocol: 'wifi-mesh',
  capabilities: ['routing', 'gateway'],
  maxHops: 10
});

// Discover peers
const peers = await discoverPeers({
  protocol: 'wifi-mesh',
  timeout: 5000
});

// Route a packet
const route = await routePacket({
  source: 'node-001',
  destination: 'node-050',
  data: Buffer.from('Hello Mesh!'),
  priority: 'high'
});

console.log(`Route: ${route.path.join(' → ')}`);
console.log(`Latency: ${route.latency}ms`);
```

### CLI Tool

```bash
# Create mesh node
wia-comm-017 create-node --id node-001 --protocol wifi-mesh

# Discover peers
wia-comm-017 discover --protocol bluetooth-mesh --timeout 10

# Route packet
wia-comm-017 route --from node-001 --to node-050 --protocol batman

# Monitor network
wia-comm-017 monitor --interval 1000

# Optimize topology
wia-comm-017 optimize --metric latency
```
