Towards Enabling Fault Tolerance and Reliable Green Communications in Next-Generation Wireless Systems

 Green communications have witnessed significant attention being paid to the next gen-eration of wireless systems research and development.  This is due to growing use of sensor- andbattery-oriented smart wireless devices.  The related literature in green communications for next-generation wireless systems majorly relies on transmission and sensing power management, but lacksa fault-tolerant centric approach. In this context, this paper presents a fault-tolerant and reliable greencommunications framework for next-generation wireless systems (FRGNWS). Firstly, maximumnode-disjoint routes from all source nodes to the base station are identified based on the hybridadapted grey wolf sine cosine optimizer. Secondly, a fault-tolerant and reliable route is selected fromthe maximum disjoint routes for each sensor node to the base station based on the hybrid adaptedgrey wolf whale optimizer.  The performance of our proposed green communications frameworkis assessed by simulation experiments considering a realistic implementation scenario and differ-ent metrics. Simulation results clearly validate the efficacy of the proposed green communicationsframework as compared to the state-of-the-art techniques.
