Abstract [en]

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.
