Mobility Management Based on the Integration of Mobile IP and Session Initiation Protocol in Next Generation Mobile Data Networks
نویسندگان
چکیده
For a mobile node that uses both Mobile IP and Session Initiation Protocol (SIP), there is severe redundant registration overhead because the mobile node has to make location registration separately to the Home Agent for Mobile IP and to the Home Registrar for SIP. Therefore, we propose two new IP mobility management methods that integrate both Mobile IP and SIP. Performance comparisons are made among previous method, which makes separate registration for the Mobile IP and SIP without integration, and our two integrated methods. Numerical results show that proposed methods efficiently reduce the amount of signaling messages related to the location registration and handoff.
