Energy Efficient Resources Allocation on Multi Rat Cognitive Radio Network Using Nanotechnology

Sabeenian Royappan Savarimuthu, Nandhini Thenmozhi Jaisankar and Manjunathan Alagarsamy


The common issue of user organization, allocation of resources, and base station (BS) implementation occurs when a network is heterogeneous (Het-Net) is helped by several radio-accessing technologies (Multi-RAT). Real-time user situations make it difficult to allocate resources in Het-Net optimally while guaranteeing that every user receives the smallest necessary information rate. Due to the current enormous development of wireless network systems and the exponential growth of data congestion, there is legitimate worry about the corresponding sharp rise in energy usage. In order to tackle these issues, the study here provides a brand-new method that combines an established and effective metaheuristic optimization approach. Consequently, the importance of energy-effective layout in multi-RAT systems is rising. Numerous radio-accessing technologies (RATs) have developed and are currently coexisting in order to serve the varied needs for the network’s infrastructure and mobile user equipment (UE). These RATs operate with different network settings and allocations of resources. A promising technique to address the issue of spectrum scarcity is cognitive radio (CR) technology. System capacity may be increased via multi-radio accessing technologies (multi-RAT). In order to increase the efficiency of spectrum and network flexibility for subsequent wireless systems, multi-RAT integrated into a cognitive Radio Network (CRN) is a potential model. Considering the novel CRN concept used in this research, in which the principal users make up the principal user channels. Concentrate the study on the CR’s Energy Effective Resources Allocation (EERA) challenge. The research recommends using the orthogonal frequency division multiple access with two-tier cross-over genetics algorithm-based searching approach (OFDMA-TTCGA) to discover a solution with the optimum processing power and bandwidth. The fundamental and crucial method employed by CR to locate unutilized airwaves is spectral sense. A spectrum detector employing the detection of energy has been suggested. Simulation outcomes demonstrate the stability and quicker convergence of the suggested approach. The effectiveness of energy use may be greatly improved with the suggestion. The results of simulations demonstrate that the suggested approaches can get performances close to the ideal solution with a great deal simpler structure and a greater efficiency of energy than a traditional spectral-efficiency-based method.
