Abstract :
Seamless handover is required in VoIP mobility services in order to limit the period of the service disruption experienced by a MN when moving between different IP subnets. Our seamless handover method involves sending multiple copies of the mobile agents to potential MN locations of movement for early authentication. Both VPN and multi-homing techniques play an important role in the reduction of the handover delay and packet loss ratio. The implementation aspect of seamless handover in mobile agent based VoIP services is provided. In the performance analyses, a comparison in the handover delay is made between the standard mobile IP mobility and our method.
