Management of household appliances and the services have been complicated by increasing of network devices recently. Therefore, Home Gateway (HGW) which manages them intensively has been expected as new consumer electronics. However, HGW has not been popular in our life because the installation cost of HGW is expensive compared with the benefits of services. In this study, we propose new home network system architecture working with not HGW but cloud computing for home management as a resolution. Basic and real-time applications are realized by M2M (Machine-to-Machine) communication between household devices under the local network area and, sophisticated and non-real-time applications are managed on the network cloud and control the household devices via internet. With some examples of home network service, proposed architecture are designed and evaluated at various points of view.
