Abstract: | With developments in voice over IP (VoIP), IP-based wireless data networks and their application services have received increased
attention. While multimedia applications of mobile nodes are served by Session Initiation Protocol (SIP) as a signaling protocol,
the mobility of mobile nodes may be supported via Mobile IP protocol. For a mobile node that uses both Mobile IP and SIP,
there is a severe redundant registration overhead because the mobile node has to make location registration separately to
a home agent for Mobile IP and to a home registrar for SIP, respectively. Therefore, we propose two new schemes that integrate
mobility management functionality in Mobile IP and SIP. We show performance comparisons among the previous method, which makes
separate registration for Mobile IP and SIP without integration, and our two integrated methods. Numerical results show that
the proposed methods efficiently reduce the amount of signaling messages and delay time related to the idle handoff and the
active handoff. |
