Method of Device Matching for QoS Based UPnP Framework in Cloud Computing Service

In recent year, rapid advancement of UPnP technology cause development of a variety of UPnP devices. In addition, various UPnP services developed for the devices. In home network environment, user needs continual UPnP service. However, the services based on UPnP are not provided continually, because of imperfect matching among the heterogeneous devices. To solve these problems, this paper proposes an automated method of matching for UPnP devices for user mobility and continual UPnP service in home network and cloud computing environments. The proposed method of automated device matching uses a mobile agent for providing reliable QoS in real-time. The mobile agent regularly searches for UPnP devices in the home network. In addition, the searched device information is registered in control system by mobile agent that monitors state of the searched device. Users use the service that is allocated from mobile agent in real-time when users access home network. To provide QoS to interdevice, mobile agent analyses relationship between user device and service device. Then, the mobile agent connect user device with service device which has high priority. Thus, user can use continual service in different environments.
