Abstract Data Transmission plays an important role in the digital world. This transfer occurs via point-to-point data streams or channels. These channels may previously have been in the form of copper wires but are now much more likely to be part of a wireless network. In here, We are using Cognitive Radio(CR) a concept on Wireless Sensor Networks(WSN) which is being used as an intelligent wireless Communication Technology having unique Capabilities of monitoring spectrum bands and detecting available channels to enable the usage of statically allocated spectrum. Furthermore, by dynamically adjusting its operating parameters, it can utilize available channels and to attack the upcoming spectrum crunch issue. Cognitive Radios can be used to find unused licensed spectrum and it can be utilized by secondary users without causing any interference to licensed users. Some of the existing techniques used in Cognitive Radio include spectrum sensing using energy detection, spectrum database, and pilot channel. In here we are using Momentum Search Algorithm technique is functioning on momentum conservation law and kinetic energy conservation law. The data to be transferred will be dynamically split and they will be scheduled for transferring. And the selection of channel will change accordingly for higher efficiency channel selection to transfer the data without loss and the transmission of data packets having higher size will have higher efficiency and the data packet consists of 8-bit for the address of data packets. It is used to Bring down the errors and damages in the data packets. Using Momentum Search Algorithm rule the user can utilize the same degree of interference as Primary users(PU) and to transfer Higher size of data packets on higher efficiency. This proposal shows the way out in achieving the first-rate performance of Data Transmission using Cognitive Radio Network based on Momentum Search Algorithm.
