What is it about?
The active development of modern wireless networks and Internet of Things (IoT) technologies requires their more in-depth study. This can be done by using simulation products and real build of the studied technology. In order to verify the reliability of the simulation results, they can be compared with real ones. This paper compares Received Signal Strength Indicator (RSSI) results in a ZigBee sensor network obtained by simulation with real results.

Why is it important?
A simulation product for a ZigBee sensor network has been proposed, which can visualise RSS and RSSI values for end sensor nodes; The RSSI results reported in the simulation and the actual ZigBee sensor network compared; The obtained results show that for 2 end devices in the network the values for RSSI obtained through the simulator are almost identical to those for the tests with a real network; The results with 4 and 6 end devices obtained through the simulator are close to those of the real network; The deviation in the RSSI values of the simulator is about 10dB compared to the real network results.
Perspectives
The results for the obtained RSSI values from the constructed ZigBee network are inconsistent in the tests for 2, 4 and 6 sensor nodes. The results of 2 sensors show that with increasing distance from the coordinator the obtained RSSI values deteriorate. This trend is not observed in the tests with 4 and 6 sensor devices. In them, with increasing distance from the coordinator, the obtained RSSI values are identical or better for some of the nodes and worse for others. This is due to the presence of external noise influences and interference between the sensor nodes, which can increase with the number of devices in the network.
