A network has been developed over a time for resource sharing called peer-to-peer network. Major task of this is to find out the objective data or files. A better scheme with good reciprocity for searching is difficult to find because its recognition is too wavering. Several methods have been found to overcome the problem and most of them were only useful to search popular objects so in the authors' paper, they proposed a Cloning Random Walker assisted by Dominating Set (Clone RW+DS) method to identify the correct data or file. In their paper, theoretical analysis shows that the system requires little amount of query messages and simulation results depicts that their system can perform a better reciprocity.
