Location based service is a positioning method that exploits the already existing infrastructures such as cellular networks or W-LANs. Increasing demand for energy efficient networks, the authors are proposing a clustering technique for compressing the radio database in login systems. The aim of the proposed technique is to reduce the computation cost and transmission load in the mobile-based implementations using Global Positioning System (GPS). The presented method is Block-based Weighted Clustering (BWC) technique, which is applied in a concatenated location-radio signal space, and attributes different weight factors to the location and radio components.
