Wireless networks can work as self sustaining by producing energy from ambient RF (radio frequency) signals. In past time, researchers have worked to design an efficient design of circuitry & components for harvesting RF energy that is appropriate for wireless components with low power. By this motivation & building a CR network model, this documentation suggested a novel technique for coexisting wireless networks in which low power mobile components are deployed in secondary network that is termed as STs (secondary transmitters), harvesting ambient RF energy from transmission through linked active transmitters in a primary type network termed as PTs (primary transmitters), where accessing the licensed spectrum in an opportunistic manner to a primary network. We have considered a model based over stochastic-geometry where STs & PTs get distributed as independent HPPPs (homogenous Poisson point processes) & communicate to their dedicated receivers over fixed distances. Every PT is linked to guard zone for protecting the dedicated receiver from interference to STs that are accumulated in harvesting zone. In this documentation, we have suggested a PSA (prioritized spectrum access) for enhancing the performance of probability of transmission.
