Wireless lighting control system is considered as an infrastructure for o ering
positioning based lighting control service. The luminaires in the system are
equipped with wireless sensors and the wireless sensor transmission for illumi-
nation control in the lighting control system are used to do indoor positioning.
Specically, received signal strength indicator (RSSI) values from these sensor
transmissions are collected at the smartphone. A simple RSSI-based indoor
positioning algorithm is proposed in this report. By combining with accelerom-
eter sensor data, the user location zone can be determined. Then a user may
be able to control associated luminaires based on its location zone. The pro-
posed indoor positioning method is evaluated via experiments in a room with
wireless sensor nodes at ceiling and simulations based on a large indoor lighting
oce space model. Experimental and simulation results show that the proposed
indoor positioning method can be used to localize a user.
