Wireless Network Localization - Optimization Processing
This paper deals with localization in wireless cellular networks. The authors performed measurement of the received signal strength in and around Brno city and stored the collected data. The localization approach uses multi-slope channel models to estimates the propagation distance from the signal strength. Results are processed by two localization techniques. The first one is geometrically based with a triangular constellation of BSs. The second one is independent on the number of connected BSs, however, more linked BSs with a triangular constellation refine the localization precision. This technique uses an optimization algorithm and proves to be universal and more accurate.
