In ubiquitous network environment, mobility is supported among various networks. When a user enjoying the media streaming service changes his attachment point, the service need to be provided continuously. In this paper, we propose a mechanism to provide seamless mobility for a user using RFID tag. We build a test bed for user mobility, and confirm that the seamless service can be provided according...

In ubiquitous network environment, the home gateway in home network will be able to support seamless service mobility about multimedia service. The multimedia service process the signal, before the transporting stream. So, we propose a multimedia signaling which supports fast signaling for the mobility of multimedia service in a home network. And we measure the latency time of signaling by simple...
Overlay multicast delivery mechanism is a new approach in which multicast functionality is implemented over application layer. However, existing overlay multicast protocols are not standardized and many restrictions occur in wireless environment. This paper addresses design and implementation of relayed multicast control protocol for 1-to-n multicast for mobile environment.
Overlay multicast delivery mechanism is a new approach in which multicast functionality is implemented over the application layer. However, existing overlay multicast protocols are not standardized and many restrictions occur when delivering high quality contents. In this paper, we propose efficient data relaying mechanism to support overlay multicast streaming services. The proposed algorithm utilizes...
