This software packet is used to co-simulate wireless netowrks and physical systems in cyber-physical system (CPS) evaluation. The details about the simulator design can be found in [1].
The wireless network simulator is built upon the open-source OMNET++ with the INET and MiXiM libraries. It enables the following features in the discrete event packet-level network simulation:
- TDMA slot allocation for periodic process variable updates
- IEEE 802.15.4-based transceiver
- Industrial wireless channel model [2]
- Co-channel interference (e.g., between IEEE 802.11 and IEEE 802.15.4 radios)
The physical system simulator is based on the Tennessee Eastman simulator C++ code [6]. It works as an independent function module in OMNET++ platform and share the same global clock with the radios (no time synchronization issues).
The latest version is 2016-05-02.
This software packet uses the open-licensed OMNET++ [3], the INET framework [4], and the MiXiM framework [5]. The physical system code is copied from the NIST TEsim repository written by Richard Candell [6].
