In the area of Wireless Sensor Networks, localization is the essential issue. Localization-discovering the location of individual sensor nodes leftovers one of the most complex research challenges. Practical solutions involving reasonable power, computation and monetary costs do not exist. Since many rising applications based on networked sensors require location awareness, a node must be able to find its location. So, Spotlight a localization system that carries high-location estimation accuracy at low cost. The system uses spatiotemporal properties of well-controlled events in the network; light in this case, to obtain locations of sensor nodes. The system is to detect the multiple events in the network and to increase the area of the sensor field by increasing the number of nodes.
