A Distributed and Parallel Sampling System for Efficient Development of Radio Map

Received Signal Strength based positioning systems can enable many potential context aware ubiquitous computing scenarios. Accuracy of such positioning is based on radio map reference database that provides mapping function between user location and signal strengths. Previously, the development of radio map remained major issue in wide scale adoption of this technology. We propose an integrated distributed and parallel sampling approach to facilitate radio map database development. Results show faster development of radio map and noticeable reduction in database size.
