Abstract
In wireless communication network to hold different types of efficient services such as electronic mail, internet, mobile user, audio and television broadcasting for the purpose of communication. Each service can have individual service quality, high efficiency, high mobility, low cost and specific frequency band of operation. The Intelligent Cognitive Radio Network is the recent advanced technology in wireless communication. The standard CRN used to achieve reliable communication and effective high efficiency spectrum sensing. In this proposed technique used to properly sensing the channel continuously, harvesting the RF energy using micro strip antenna, when data will be transmitted in the Primary User channel so this technique is called as RF powered CRN. The un-allocated Secondary User channel utilized the harvested power from the Primary User for the purpose of effective channel sensing and data transmission. The RF powered CRN technique used to improve the efficiency of channel sensing and energy harvesting. Here energy harvested from GSM band Primary User data transmission. The new RF powered CRN method used to directly find the Primary User and Signal Noise Ratio (SNR).
