System modelling and improvement of radio over fiber of the internet of things through quantum entanglement

Abstract

The first part of the contribution that is made by this thesis is to expand on how new paradigms of fire detection in the IoT environment have been created. Clarifying how it had intended the physical distribution of the Remote Antenna Unit (DRAU) architecture. These observations show how the architectures of distributed RAUs protocols of BRAUS in IoT-RoF are expanded to new selection metrics. Under distance two performance measures have been considered and they include number of RAUs and fiber optic attenuation, path loss factor. Following the simulation and numerical analysis of the presented desirable protocols the obtained results indicate that the outage probability minimization of the desirable protocols is less than the work [18]by 65% On the equal basis, bandwidth efficiency of the desirable protocols is found to be higher than recent works 34%. The second contribution of this thesis is the proposed A new quantum MAC protocol has been designed and implemented here in this thesis and named as Quantum Entanglement-based MAC protocol, abbreviated as QE-MAC. Four entangled states are used to form the control packets of MAC classical protocol and the transmitted data on the classical channel. ACK, RTS and CTS control packets are not employed here but state transitions are used instead. This approach has some benefits in that it minimizes the delay and collision issues conventionally associated with control packets and in result boosts the performance of the networks. The delay, duty cycle, and power consumptions of the proposed QE-MAC protocol are defined and calculated as follows: For this reason, all of these reduce the proposed approach delay and power consumption by 35% compared to the related work in the literature. The third contribution of this thesis is the analysis of the performance of the Radio-over Fiber (RoF) with energy harvesting (EH) of cooperative communication technique. The influence of small, large-scale fading, and large-scale fading is analyzed by using mathematical modeling. For the Radio-over Fiber (RoF) with energy harvesting (EH) of cooperative communication technique, we use outage probability as our performance measure. Last but not the least, the results depict that cooperative communication enhances the capacity of the system than the direct traditional communication with energy harvesting by 22%. The fourth contribution brings the ICHC-RoF into the field for the first time. The Outage probability mathematical model is described next: Furthermore, an analysis of the throughput performance of the offers’ proposed protocol is also derived mathematically. Theoretical calculations reveal that the proposed ICHC-RoF system has superior performance and enhancements of 35% from simulations.
