Development of an indoor location-based system using sensor networks

In indoor location-based systems, the increment of the number of deployed beacon nodes for high accuracy results in many collisions and much interference among signals. In this paper, we propose an indoor location-based system using sensor networks that contain the localization scheme based on the law of cosines and the on-demand beacon management mechanism. Our experiment results show that our indoor location-based system achieves high accuracy even though it is using a small number of sensor nodes.
