Performance evaluation of the radio database compression for accurate energy efficient localization

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, a clustering technique for compressing the radio database in Login Systems is proposed here. The aim of the proposed technique is to reduce the computation cost and transmission load in the mobile-based implementations. The presented method uses a Pattern Clustering (PC) technique, which is applied in a concatenated location-radio signal space, and attributes different power factors to the location and radio components. The Experimental Architecture will be produced to evaluate the results and the efficiency. Also, it improves the performance.
