Spectrum Aware Routing Protocol in Cognitive Radio Network using the concepts of TDMA

Abstract: In the advance field of technology, there is a limited spectrum allocation and we need to communicate in each field. So we have cognitive radio network with us to make us able to communicate by using the frequency spectrum of licensed nodes. In Cognitive radio network primary nodes have licensed frequency while secondary nodes do not have. So secondary users need frequency of others nodes to make communication possible. In CRN secondary nodes uses the frequency spectrum of primary nodes.Not only this we have several concepts to make communication between secondary nodes while in this paper we are using spectrum aware routing protocol in cognitive radio network using the concepts of TDMA.
