System Overview

System Overview

High-Level Architecture

The system architecture comprises three main layers:

1. Edge Layer: Consists of IoT sensors deployed in forest areas equipped with LoRaWAN connectivity for low-power communication. These sensors collect environmental data such as temperature, humidity, smoke density etc.

2. Cloud Layer: Data from edge devices is transmitted to GCP where it undergoes preprocessing, storage, and analysis using AI models. This layer also manages API interactions between different system components.

3. User Interface Layer: A publicly accessible dashboard provides real-time wildfire alerts based on processed data from GCP.

Key Components:

- IoT Sensors (Edge Devices)

- LoRaWAN Network Server

- GCP Services (Data Processing Pipeline)

- AI Risk Modeling Engine

- Public Alert Dashboard


Component Architecture

Component Architecture

Edge Devices (IoT Sensors)

These devices are equipped with minimalistic hardware due to constraints such as max 2MB RAM:

- Utilize LoRaWAN protocol for long-range communication while conserving power.

- Sensor suites include thermal imaging cameras alongside traditional environmental sensors.

Failure Modes:

- Power failure due to battery depletion or environmental factors like extreme temperatures.

LoRaWAN Network Server

Handles communications between numerous edge devices:

Failure Modes:

- Network congestion leading to delayed or lost messages during peak fire season loads.

GCP Services

Includes BigQuery for storage, Cloud Functions/Run for serverless compute executing data preprocessing tasks:

Failure Modes:

- Service outage at any point within the GCP infrastructure leading to delays in processing incoming sensor data.

AI Risk Modeling Engine

Utilizes machine learning algorithms hosted within GCP:

Failure Modes:

- Model prediction inaccuracies if training data does not match real-time conditions adequately.

Public Alert Dashboard

Web application hosted potentially outside of GCP but integrating via RESTful APIs:

Failure Modes:

- User interface errors due either poor frontend design or backend connectivity issues resulting in stale information being displayed.


Data Flow & APIs

Data Flow & APIs

Data flow starts from edge devices sending raw environmental readings over LoRaWAN which are ingested into GCP's BigQuery storage after being anonymized per GDPR requirements:

Security & Compliance

Security & Compliance

Measures implemented across all layers ensure compliance particularly focusing NIST IR 8320 standards critical crisis systems operation alongside GDPR:

Security Measures:

- Encryption during transmission between Edge Devices through Lora WAN up till secure ingestion into Big Query ensuring no interception possible enroute,

- Role-based access control limiting sensitive operations only authorized personnel thereby minimizing insider threats,

- Regular security audits against latest known vulnerabilities especially since dealing live emergency situations where uptime paramountcy cannot be overstated enough.,

Compliance Safeguards:

- Adherence NIST IR 8320 protocols by designing resilient yet secure systems capable handling crises without compromising operational integrity,

- Ensuring GDPR compliance anonymizing personal identifiable information before storing analyzing thus safeguarding individual privacy rights regardless jurisdictional boundaries involved therein.,

Ensuring these safeguards place strengthens trust among stakeholders knowing their needs considerations fully accounted when deploying such critical infrastructure aimed saving lives protecting property amidst natural disasters like wildfires..
