Abstract:
As the progress of computing and wireless techniques, mobile communication has changed the modern life style, e.g., checking e-mails on the bus or enjoying real-time streaming service in the train. Traditional network services and environment must be able to handle the handoff process, i.e., transition from one domain to another, due to mobility. In order to let users access the Internet anywhere, past works focus on the handoff process at lower layers. Regarding the 3-tier architecture, proxy servers can improve the quality of service (QoS). The handoff process at lower layers does not consider how to switch from one proxy to another one dynamically. This kind of handoff is defined and called “proxy handoff”. In this talk, I will present my study in the topic of proxy handoff. Key issues about proxy handoff are introduced first. Different solutions have been proposed to handle the proxy handoff process, including server-driven, client-driven, etc. From the observation and analysis from my works, proxy handoff is necessary and able to improve the QoS of applications, especially for multimedia streaming. Finally, with the advance of mobile techniques and variety of communication scenarios, I will also introduce some possible future works of proxy handoff for providing networking applications and services in the vehicular networking environment.
