PJON (Padded Jittering Operative Network)

PJON implements a totally software emulated network protocol stack in around 1500 lines of code, thanks to the strategies abstraction it can work nominally with any data link is in use and can be applied in a variety of media and applications. This library can be cross-compiled (-std=c++11) to work with any Arduino compatible device, linux or windows x86 machine.

Thanks to the interfaces abstraction, PJON can be easily ported on any MCU/architecture exposing random generation, timing and IO system calls (for example on Arduino: random, micros, pinMode).

Strategies abstraction

PJON codebase uses strategies to physically communicate through the medium used, abstracting the data link layer from its procedure. A Strategy is a class containing the back-off configuration and a set of methods able to send and receive messages; 7 strategies are available to communicate data through various media. Take a look at the strategies video introduction for a brief showcase of their features.
