## 1. Network Design

### 1.1 Coverage Plan

 municipality covers ~75 km2 (urban center ~12 km2).

**Zone Structure:**

| Zone | Area (km2) | Nodes | Description |
|------|-----|-----|---|----------|
| Zone A (Center) | 2 | 60 | Historic center, marina |
| Zone B (West) | 3 | 50 | Industrial, residential |
| Zone C (East) | 3 | 50 | Commercial, tourism |
| Zone D (South) | 2 | 40 | Port, warehouses |
| Zone E (North) | 2 | 40 | Residential, schools |
| Zone F (Surrounds) | 3 | 60 | Outskirts, approach roads |
| Total | 15 | 300 | Core mesh coverage |

### 1.2 Node Deployment Strategy

**Core Archival Nodes (20 units)**
- Deployed at strategic elevation points
- Connected to fiber backbone
- Each serves 4-6 zones
- Located: municipal buildings, telecom centers, elevated sites

**Edge Archival Nodes (80 units)**
- Deployed at neighborhood level
- Connected via WiFi mesh to gateways
- Each serves ~1 km2 area
- Located: community centers, schools, commercial buildings

**Gateway Nodes (14 units)**
- Internet uplink points
- Connected to fiber and cellular backhaul
- Strategically distributed across the city
- Redundant links (2+ providers per gateway)

**Micro Nodes (86 units)**
- Specialized by service area
- Low-power, edge computing
- Deployed at business locations, delivery hubs
- Service-specific: health, commerce, logistics nodes

## 2. Deployment Procedures

### 2.1 Node Installation Checklist

- [ ] Site assessment complete (power, network, elevation)
- [ ] Node hardware unboxed and tested
- [ ] Node flashed with OS image
- [ ] Node powered on and boot confirmed
- [ ] Network connectivity established
- [ ] Mesh join confirmed (gossip protocol)
- [ ] Data storage formatted and RAID status OK
- [ ] Solar/UPS power system connected
- [ ] Node certificate issued and verified
- [ ] Node visible in network dashboard

### 2.2 Mesh Bootstrap Sequence

1. **Gateway nodes** connect to fiber/cellular backhaul
2. **Core nodes** form primary mesh backbone (fiber-connected)
3. **Edge nodes** connect to gateways via WiFi mesh
4. **Micro nodes** join via LoRa or WiFi
5. **Service mesh** establishes connections between layers
6. **Monero wallet** initialization and test transaction
7. **Node registry** populated with all nodes
8. **Monitoring** systems come online

### 2.3 Zone Deployment Priority

1. Zone A (Center) - first 2 weeks
2. Zones B and C - weeks 3-4
3. Zones D and E - weeks 5-6
4. Zone F - weeks 7-8
5. Full mesh connectivity verification - weeks 9-10

## 3. Monitoring and Operations

### 3.1 Monitoring Components

- **Node health:** CPU, RAM, disk, power, temperature
- **Network health:** link quality, latency, packet loss
- **Mesh health:** node count, routing table, gossip status
- **Service health:** uptime per service, availability
- **XMR network:** wallet balance, tx rate, node fee income

### 3.2 Alert Levels

| Level | Condition | Response |
|-------|----------|---|-------|
| INFO | Normal | Logged |
| WARN | Degraded | Monitor, schedule maintenance |
| ERROR | Partial | Dispatch, <15 min response |
| ALERT | Critical | On-call response, <5 min |
| DOWN | Node offline | Auto-failover initiated |

### 3.3 Maintenance Schedule

- **Daily:** Automated node health checks
- **Weekly:** Mesh route optimization
- **Monthly:** Battery/UPS health checks
- **Quarterly:** Full node diagnostics
- **Annually:** Hardware inspection, firmware updates

## 4. Network Configuration

### 4.1 Key Network Parameters

| Parameter | Value | Notes |
|-----------|------|-----|
| Mesh SSID | NodeZero | WiFi mesh |
| IPv6 Prefix | fd00:funchal::/48 | |
| LoRa Frequency | 868 MHz | EU |
| Mesh Port | 9001 | |
| Bootstrap Port | 9002 | |
| Beacon Interval | 500ms | |
| TTL | 64 | |
| MTU | 1492 | |
| DNS | mesh.local | Internal |
| External DNS | 1.1.1.1, 8.8.8.8 | |

### 4.2 Power Management

- Solar panels: 200W per node
- Battery: 24V 100Ah LiFePO4
- UPS capacity: 8 hours autonomy
- Power management: automatic sleep/wake cycles
- Low power mode: nodes enter sleep during low activity

## 5. Mesh Services Integration

### 5.1 Service Discovery

Each node registers available services. Discovery uses mesh gossip:
- Service announcement on startup
- Periodic heartbeat updates
- TTL-based expiration
- Cross-service dependency resolution

### 5.2 Message Routing

- **Direct routes:** Known nodes, shortest path
- **Mesh routes:** Fallback via Gossip
- **External routes:** Through gateways
- **Routed services:** Rides, Housing, Commerce, etc.

### 5.3 Redundancy Strategy

```
Primary path: Node -> Local Gateway -> Fiber -> Internet
Fallback 1:   Node -> Local Gateway -> Cell -> Internet
Fallback 2:   Node -> Neighbor Gateway -> Fiber -> Internet
Fallback 3:   Node -> Satellite (if equipped) -> Internet
```

- Automatic failover between paths
- Link quality monitoring (every 10 seconds)
- Bandwidth pooling across available paths
