Operating System for Petri Nets-Specified Reconfigurable Embedded Systems
Richta Tomáš, Ing., Ph.D., FIT (FIT), UITS (FIT)
Generation of code from Petri nets-based specification mainly depends on the proper decomposition of the whole system model to a set of subnets, which is called partitioning problem. In our experiment we started from the MULAN architecture for multi-agent systems modelling defined by Cabac et al. It divides the model of the system into four levels of abstraction - infrastructure, agent platform, agents, and protocols. We have defined a simplified but similar layered architecture, which is inspired by MULAN, but oriented towards distributed control systems modelling and implementation. Targeted application area - distributed control systems based on Wireless Sensor Networks - led us to introduce the fifth level of abstraction, which we call Node level. This level serves as a hardware abstraction layer and provides support for other levels of the system. Our specific contribution is the idea of code generation, where each level of the model is mapped to the target implementation in a level-specific way which conforms to our main goal that is dynamic reconfigurability of the system. The proposed architecture then enables incremental changes within the system specification and implementation during its run-time.
