Power Efficient Relay Method for Green Communication

Abstract

Transferring data between the two or more systems plays a major role in wireless communications. Every data which is sent through the network should be secured. In Relay Networks, Secure transmission of data between transmitter and receiver relays with less power consumptions and Secure Transmission in Spectrum Sharing is done. Previously ADHOC network was used. In that the systems will stick to one place only. Hence radiation and power consumption will be high. Data will be transferred with delay. So, for less power consumption, relays can be used. Due to the relays, power consumption will below. And also, data gets transferred fast. It can best uck to a place and also can be moved. A radio that can change its transmitter parameters based on the environment in which it operates is called a cognitive radio. A relay network is a broad class of network topology commonly used in wireless networks, where the source and destination are interconnected by means of some nodes. In such a network the source and destination cannot communicate to each other directly because the distance between the source and destination is greater than the transmission range of both of them, hence an intermediate node like relay can be used.
