The Virtual Device: Expanding Wireless Communication Services Through Service Discovery and Session Mobility

Shacham, Ron; Schulzrinne, Henning G.; Thakolsri, Srisakul; Kellerer, Wolfgang

We present a location-based, ubiquitous service architecture, based on the Session Initiation Protocol (SIP) and a service discovery protocol that enables users to enhance the multimedia communications services available on their mobile devices by discovering other local devices, and including them in their active sessions, creating a 'virtual device.' We have implemented our concept based on Columbia University's multimedia environment and we show its feasibility by a performance analysis.
