Packet:

Packet is designed for real-time low-overhead data transmission over the Internet. It transmits and receives raw blobs. It's easy to use, and we provide both C++ and Python implementation. Currently, we tested transmission jpg, json, and double number. It is a potential alternative for ROS subscriber and publisher over WIFI and Internet.

Our Strength:

• support both Python and C++
• Delay is as small as 10 milliseconds (based on our experiments)
• Send data over WIFI
• Send large data object

How to Use:

In the example folder, we provide examples for both C++ and Python. To run the example in C++, you need to install eigen3 and opencv library. The publisher in the example sends a image, a double, and a JSON object, and the subscriber will store the image, and print the double and json.

Tested Functions:

• C++ publisher with C++ subscriber over WIFI.
• Python publisher with Python subscriber over WIFI.
• C++ publisher with Python subscriber over WIFI.
• Python publisher with C++ subscriber over WIFI.
