Wireless location finding is one of the key technologies for wireless sensor networks. Global Positioning System (GPS) is the technology used but it can be used for the outdoor location. When the authors deal with the indoor locations GPS does not work. Indoor locations include buildings like supermarkets, big malls, parking, universities and locations under the same roof. In these areas the accuracy of the GPS location is greatly reduced. Location showed on the map in not correct when the GPS is used under the indoor environments. But for the indoor localization it requires the higher accuracy SP GPS is not feasible for the current view.
