With the increasing use of small, lightweight, powerful and multi-radio devices, and the omnipresence of wireless networks such as WiFi, the pave to ubiquitous computing is gradually emerged and realized. Ubiquitous computing allows users to access their services using any device, anytime, anywhere in a very flexible manner based on the current context. In particularly, services could be started on one device that attaches to one network and later be easily switched to another device connected to another network, commonly known as session mobility. In this paper, we describe our concept of seamless session transfer for real-time application such as VoIP and IPTV, and our prototype implementation of such concept using both WiFi and Bluetooth approaches, with qualitative and quantitative performance comparison.
