Major issue in wireless sensor networks is Localization and the study is done over years. With the real time experience GreenOrbs, to know about the climatic condition in the forest; they are unable to get the proper data sitting remotely with the current technique employed for knowing weather conditions at forest. In the authors' proposed work, they use (CDL) Combined and Differentiated Localization approach that exploits range-free approach using Received Signal Strength Indicator (RSSI). Noticeable change observed with the new approach is that better ranging quality when compared with the existing approach. CDL in addition incorporates local filtration, virtualhop localization and ranging quality aware calibration.
