Learning project - Real-time sensor data streaming over a custom TCP protocol

The project

This is a learning project to understand how to stream sensor data over a custom TCP protocol. The project is divided into two parts: the server and the client. The server is responsible for receiving sensor data from multiple sensors and logging it first to the console and then to a file. The client is responsible for sending sensor data to the server. (The client is more like a dummy sensor for now)

The protocol

The reason why I chose to send the data using a custom protocol is to understand how to create a protocol from scratch. The protocol is a simple one and is as follows:

Message format

• Sensor Data format
  • Message Type (1 byte) - 0x01 (unused for now)
  • Sensor ID (1 byte) - 0x01 to 0xFF
  • Timestamp (4 bytes) - Unix timestamp in seconds
  • Data Length (4 bytes) - Length of the data
  • Data (Variable length) - Sensor data

Message types

• 0x01 - Sensor Data
• More to be added...

Features

• Server listens for incoming connections
• The sensor client connects to the server
• Server receives sensor data from the client
• Server can handle multiple clients
• Server logs the sensor data to the console
• The client retries to connect to the server if the connection is lost
• Server logs the sensor data to a file

How to run?

1. Clone the repository
2. Run the server
   • Run go run server/server.go
3. Run the sensor client
   • Run go run client/sensor.go
