A fault-tolerant and energy-efficient design of a network switch based on a quantum-based nano-communication technique

Green communications and networking present innovative designs to reduce energy usage in the information and communication technology sector. Device-to-device communication over switched networks can also be viewed as one of the research possibilities to improve energy efficiency in green communication networks. On the other hand, Quantum Dot Cellular Automata (QCA) is a new topic in nanotechnology that allows circuits to be constructed at the nanoscale to solve the restrictions of the current technologies, such as high energy usage and delay; therefore, it is very suitable for green communications. QCA opens up a whole new world of possibilities for generating fundamental gates in digital electronics with the least hardware complexity. One of the primary obstacles in employing such innovation is the overall likelihood of flaws and adequate physical execution in the QCA. This research covers the fundamentals of nanotechnology and relevant topics on fault-tolerant nano communications in green communications in this discipline. The circuit-switched network is critical for transmitting the input signal across multiple consumers throughout a dispersed communication network. The construction of a modern fault-tolerant circuit-switched network with low energy consumption centered on QCA and green communications is demonstrated in this study. The layout is made up of just one layer. This investigation offers a novel fault-tolerant crossbar switching to build this communicating network. The fault-tolerant rate of the switch against missing cell faults was researched in order to determine the best switch. The QCADesigner-E tool created and analyzed the energy dissipation and verified the simulation outcomes. The suggested switch is more fault-tolerant and greatly optimizes energy consumption, according to simulation findings.
