In recent years, home appliances network is expected because it enables appliances to connect to a network and improves their convenience, and we are examining home appliances network system using Bluetooth as communication media. Although it consists of just a few appliances now, it is required to add many small appliances such as security sensors to the network. However, Bluetooth has a restriction that only seven nodes can connect to one access point simultaneously. In this study, we adopted the method using Park Mode which is one of the Bluetooth power-saving modes, and proposed the Park Mode control algorithm to realize a large-scale-izing of a Bluetooth home appliances network.
