Due to the growth and spread of wireless devices in the unlicensed spectrum bands, such as ISM, the bands become more and more crowded and therefore affect the performance of the wireless networks negatively. Thus, the cognitive spectrum access principles are required to utilize the existing spectrum bands more efficiently. There are many advantages of cognitive radio technology but there exists some obstacles like the CRT Cognitive Radio Technology is used over a heterogeneous radio spectrum of licensed and unlicensed spectrum bands and as for survey huge work in done in licensed spectrum bands and very small of work done in the amalgamation licensed and unlicensed bands for data transportation.
