In a smart and decision making environment the location information of the sensors and devices under monitoring and control, is very much important, otherwise the sensed data becomes meaningless. This paper proposes three intelligent algorithms namely differential evolution localization algorithm, firefly localization algorithm, and a hybrid firefly differential evolution localization algorithm for wireless sensor networks localization problem. The proposed algorithms are range based and distributed localization algorithms. The algorithms are studied, analyzed and compared with respect to time complexity, convergence and accuracy of the estimated location information.
