Localization is the subject matter that has allured the attention of many researchers in the field of wireless sensor network. It is the process of assigning or computing the location of the sensor nodes in a sensor network. Since the sensor nodes are randomly deployed, it is very important that they localize themselves, as the manual deployment of sensor node is not feasible. Thus in this paper, we find out the solution for localizing the sensor nodes. We have developed a novel model that first finds the distance of the sensor nodes then it finds the location of the unknown sensor nodes in power efficient manner.
