Abstract—For the majority of the applications of WSNs, it is desirable to know the location of sensors. In WSNs, for obtaining this kind of information we need localization schemes. Localization techniques are used to determine the geographical position of sensor nodes. The position parameters of sensor nodes are also useful for many operations for network management, such as routing process, topology control, and security maintenance. So, it is very important that every node should reports its location information very accurately. As we know that GPS is very accurate in location determination but it is expensive in terms of cost and energy of nodes, so it is not useful in WSNs. There are so many localization techniques, including range-based and range-free, have been proposed to calculate positions for randomly deployed sensor nodes. Accuracy of localization techniques is most important before implementing it. With specific hardware, the range-based schemes typically achieve high accuracy based on either nodeto-node distances or angles. In this paper, our main focus is on the range-based localization. Precisely, in order to helps the network designers to find out which techniques/algorithms are suitable for their applications, the most popular range-based localization techniques are classified and compared.
