Investigating delay of the media access control protocols for IoT‐RoF using quantum entanglement
IET Networks, Volume 13, Issue 4, Page 324-337, July 2024.IoT‐RoF QE‐based: MAC Protocol Delay Study. Abstract One of the significant challenges of the Radio over fibre (RoF) Medium Access Control (MAC) protocol is the propagation delay. This delay can lead to serious issues, such as higher propagation delay resulting in collisions and unnecessary retransmissions.

Expert Systems, Volume 41, Issue 2, February 2024.Abstract One of the most common attacks is man‐in‐the‐middle (MitM) which, due to its complex behaviour, is difficult to detect by traditional cyber‐attack detection systems. MitM attacks on internet of things systems take advantage of special features of the protocols and cause system disruptions, making them invisible to legitimate elements.

Performance Analysis of DP‐QAM‐Based Optical OFDM PON Employing Optical Multicarrier
Journal of Engineering, Volume 2024, Issue 1, 2024.This work proposes a new hybrid bidirectional standard single mode fiber (SSMF)/free space optical (FSO) dual polarization quadrature amplitude modulation (DP‐QAM) employing optical orthogonal frequency division multiplexing (OFDM). An optical multicarrier generator (OMG) source is utilized. The suggested model is simulated using VPI photonics software.
