摘要：Emerging wireless applications needs more spectrums space to tackle the rapid growth of users. Outside of radio band in spectrum will be hard to utilize for data transmissions in terms of hardware requirement. Cognitive radio research considers the Current Spectrum underutilization and provides a better model for next-generation wireless environment. Since, the cognitive radio and its policies violate the static spectrum allocation i.e., Current Wireless networks policy, many challenges are in front of us to accomplish a better cognitive radio wireless environment. One of the major challenges is secure transmission and optimal free channel selection for un-interrupt data transmission. In this article, we have proposed an efficient free-channel selection scheme for improving QoS of Cooperative Cognitive Radio Networks. The proposed model has been derived as an integrated approach by using successful MCDM techniques such as EFAHP and TOPSIS. Also, we have proved the optimality of the proposed integrated technique with other parallel channel selection techniques with various scenarios.
