A Study for Finding Location of Nodes in Wireless Sensor Networks

چکیده
The popularity of Wireless Sensor Network (WSN) has increased tremendously in recent times. WSN has the potential to connect the physical world with the virtual world by forming a network of sensor nodes. Sensor nodes transmit the data to the other nodes present in their range. Localization in radio networks has been an intense area of research for quite some years, for military, civil and sensor networks. To discover the location of neighbour nodes is an important task. Using location information is very beneficial in terms of energy consumption. Location of the nodes can be obtained directly through GPS (Global Positioning System) or by applying mathematical calculations. This paper performs detailed study for the different localization algorithms through which a position of sensor nodes or sink can be calculated. KeywordsGPS, Localization, WSN.
