It is designed be portable for various platforms, including simulation environments and hardware platforms including CometOS. The IEEE 802.15.4 standard with its widespread usage in wireless sensor and actuator networks was recently extended by several techniques that allow reliable data transmission for critical applications, such as industrial plants. This includes the Deterministic and Synchronous Multi-channel Extension (DSME) that allows for distributed assignment of time slots on multiple channels. The project page including source code and live results is available at www.openDSME.org.
