Abstract :
As mobile wireless networks increase in popularity and pervasiveness, seamless mobility is an important paradigm 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 affects of the handoff latency in WiFi network environment. The simulation results reveal that the proposed scheme has a great performance in packet loss and higher QoS during handoff.
