System-level simulator of Bluetooth Low Energy version 5

This simulator is written in C++ and developed to work in MiXiM framework of the OMNeT++ engine. This simulation, which simulates the PHY and MAC layer of BLE 5, is developed on top of BLE 4.2 simulator. This simulator has been used for publishing the following article:

  • B. Badihi, F. Ghavimi and R. Jäntti, "On the System-level Performance Evaluation of Bluetooth 5 in IoT: Open Office Case Study," 2019 16th International Symposium on Wireless Communication Systems (ISWCS), Oulu, Finland, 2019, pp. 485-489, doi: 10.1109/ISWCS.2019.8877223.

The following features of BLE5 have been developed:

  • New PHY layers including, LE Coded S2LE Coded S8LE 2M PHY in addition to LE 1M PHY.
  • Channel Selection Algorithm 2#.

In addition to the above-mentioned features, a dedicated decider for BLE in PHY layer, flow control in MAC layer and new auxiliary advertising packets are developed. It is worth mentioning that this simulator is developed and tested with OMNeT++ version 4.4.1 and MiXiM version 2.3. The higher versions of OMNeT++ may or may not work with the tool.
