Social graph analysis using Bluetooth radio transmitters called “Beacon” is discussed in this paper. Each person carries the beacon and a smart phone; the smart phone is performed for a receiver. Someone’s smart phone can recognize another person’s beacon and the distance between the two persons. As the result, our social graph can be generated using those data. Graph pruning is necessary, and we discuss how to determine the two threshold parameters for the distance between two persons and the received signal reception frequency. We show one guideline to determine the two threshold. A system simulation is shown in our experiments.
