In present current situation Cognitive Radio (CR) is new evolving and very popular technology due to its intelligent working.It has become one of the best available options for many of the problems faced today in other technologies.In addition to this, for data security, this is most preferable option.In this paper we have presented a unique and generalized solution for one of the attack i.e. blackhole attack.We have dealt in this paper with parameters PDR and Throughput.This paper also tells about the importance of cognitive radio in present scenario about various features of CR like spectrum sensing, management, mobility, sharing and many more.There is description about the blackhole attack.Then in later part of the paper we have shown through graphs our simulated result in which there is comparative analysis of the previously applied algorithm.There is improved version of the algorithm and it is showing the better performance as we got result in our simulations.
