Positioning of Node for Static WSNs

The development of wireless technologies and micro electromechanical systems has initiated the success of wireless sensor networks. This kind of networks is composed of many sensors which are deployed heavily in an area of interest. They collect and disseminate the required data for many applications. Hence, the research on wireless sensor networks is actually an interesting and attractive area, as several problems must be overcome. Determining the physical localization of a sensor is a fundamental function and a challenging issue that was addressed by many applications. Thus, numerous systems and algorithms of localization were proposed in the literature. In this paper, we study the basic technologies used for the localization of sensor nodes. Then, we examine some important algorithms while summarizing the parameters that we use for their classification. At the end, we conduct a comparison between all the studied algorithms, and we are going to give the directions of our future research.
