Video telephony, seamless, service mobility, ubiquitous computing
In this paper, we design and implement a framework for seamless video telephony service in ubiquitous computing environment. We use video telephony using personal computer (PC), mobile devices, and mobile phones and so on. But it is difficult to seamlessly move the service among devices during a call between users. Proposed video telephony mechanism can provide continuous service among devices. Using this scheme, users can utilize the video phone services flexibly from one device to another in ubiquitous environment.
