Secured communication among IoT devices in the presence of cellular interference

in a relay aided IoT system in the presence of cellular interference.
Here the IoT devices share the same spectrum resources
as the cellular users (CU) and an eavesdropper attempts to
extract the confidential messages from these devices. For this
system, the expressions for the mean square errors (MSE) at the
legitimate and eavesdropping users have been formulated. The
precoding matrices are then optimized in such a manner that the
MSEs at the legitimate receivers are kept small, whereas MSE
at the eavesdropper is large. The analysis shows that increasing
interference from CU can degrade the MSE performance at
the eavesdropper. Also, it can be seen that with increasing
distance between the devices and the eavesdropper, the MSE
at the eavesdropper increases. On the other hand, increasing the
distance between the CU and the eavesdropper decreases the
MSE at the eavesdropper. Finally, numerical simulation results
are provided to verify the validity of the analysis.
