Abstract :
As mobile wireless networks increase in popularity and pervasiveness, seamless mobility is an important issue for uninterrupted services in ubiquitous network environments. In this paper, we propose a zero packet loss handoff mechanism for real-time streaming services, which is based on the SIP protocol cooperated with mobile agent, multicast, and buffering technique to overcome the impact of handoff delay in SIP-based wireless networks. The simulation results reveal that the proposed scheme has a great performance in packet loss and higher QoS during handoff. Furthermore, we realize and evaluate the proposed scheme by applying MP3-music streaming on the system.
