IoT service in home domain needs common and
effective ways to manage various appliances and devices. So, the
home environment needs a gateway that provides dynamical
device registration and discovery. In this paper, we propose the
IoT Home Gateway that supports abstracted device data to
remove heterogeneity, device discovery by DPWS, Autoconfiguration
for constrained devices such as Arduino. Also, the
IoT Home Gateway provides lightweight information delivery
using MQTT protocol. In addition, we show implementation
results that access and control the device according to the home
energy saving scenario.
