Wireless Sensor Networks, Sensor Nodes, Anchor Nodes, Localization, Algorithms.Abstract
The important function of a sensor network is to collect and forward data to destination. The target nodes or normal nodes send out information at their location to the nearby base station or anchor node. It is very important to know about the location of collected data being received. This kind of information can be obtained using localization technique in wireless sensor networks (WSNs). Localization is a way to determine the location of sensor nodes. Localization of sensor nodes is an interesting research area, and many works have been done so far. It is highly desirable to design low-cost, scalable, and efficient localization mechanisms for WSNs. For more accurate results the localization algorithms were improvised over time. In this paper we list all the localization algorithms, their concepts and advantages over the previous methodologies.
