- Abstract
- Mobile IP provides a simple and scalable macro mobility solution but lacks support for fast handoff control in the micro-domain. However, the third-generation cellular system requires seamless macro/micro mobility support. A lot of micro-mobility protocols have been proposed to complement the Mobile IP capability by providing fast, seamless, and local handoff control. Cellular IP also provides seamless mobility support in a limited geographical area. However, the semi-soft handoff mechanism of Cellular IP causes packet loss and duplication problems due to the difference in propagation delay between the new path and the old path. In this paper, we present an efficient handoff mechanism in the micro-domain. The proposed handoff mechanism uses the SCD (Suitable Cross Delay) to minimize packet loss and duplication during the handoff. The proposed mechanism is verified by performance evaluation through NS-2 simulation.
