Abstract: | In this paper, we present a mobility management scheme for real-time multimedia sessions over heterogeneous wireless networks.
Most approaches in the current literature use Mobile IP (MIP) or Session Initiation Protocol (SIP) to maintain real-time sessions
during mobility. In this paper, we analyze MIP and SIP in terms of the mobility rate, packet loss and packet overheads in
the user plane and propose a mechanism by which the network can choose the optimum protocol for mobility management. We perform
the analysis for constant bit rate (CBR) as well as for variable bit rate (VBR) traffic. We show that for CBR traffic, the
proposed mechanism leads to 12–35% improvement in the system capacity, while for VBR traffic, capacity improvements ranging
from about 35–50% can be obtained. Our proposed approach and the analysis are applicable to handovers between different IP
domains both in homogeneous as well as in heterogeneous wireless networks. |
