With the advancement of Cognitive Radio Network (CRN), localization of primary users progress the improvement of network performance with respect to power adoption and reliability. Moreover, CRN localization is essential because storage energy of CR devices is limited. By considering these issues, we propose an Energy Efficient Cooperative Localization approach (E2- CL) in CRN, which is used for placing Primary User (PU) position with the help of a mobile aided CR. Moreover, communication among CRs cooperation that leads to demand of more energy, a mobile CR is allowed to manage the overall positional accuracy and wake up minimum number of CR to collaborate CR manager. We evaluated the simulation results for the proposed Energy Efficient Cooperative Localization (E2- CL) approach which achieves better performance compared to existing Cooperative Localization (CL) with respect to energy efficiency.
