Abstract

In mobile computing environments; the goal is to provide continuous connectivity as a mobile host moves from one network to another – often referred to as terminal mobility. All the needed reconnection occurs automatically and non-interactively (Handley at al.; 1999). Terminal mobility can be achieved by exploiting mobile IP (Perkins; 1998) to provide mobile users the convenience of seamless roaming. Another major requirement for full mobility support is the need of an architecture that enables automatic discovery of the user location which changes with mobility of the user – a feature often referred as personal mobility. New application-layer protocols such as SIP (Handley et al.; 1999) can be used to provide this personal mobility.
