Abstract :
Wireless VoIP services require not only end-to-end transmission delay between end users but also small handoff delay between heterogeneous networks. This study designs and implements a SCTP-based mobile VoIP system in a campus network. The multi-homing capability and dynamic address configuration extension of SCTP are applied in the VoIP system to provide seamless handoff. Also, IEEE 802.21 specifies 802 media access-independent mechanisms (MIH) to optimize handoffs between heterogeneous 802 systems and cellular systems. The proposed VoIP system combines SCTP and 802.21 MIH function to improve the performance of handoff in a campus network
