Design, Implementation and Verification of an UMIP Based Multihomed Mobile Network Framework

The new generation of broadband cellular network technology together with WiFi makes the high-quality networking dependent services such as video streaming available on mobile devices. However, the leverage and handover in application layer among heterogeneous wireless networks still lacks of practical solutions. With the help of UDP based mobile IP protocol, this paper proposed a framework to allow a mobile device to work under cellular as well as WiFi network simultaneously, i.e., enabling the functionality of multihoming on this device. By a demonstration with a video application on an Android phone with dual networking interfaces, the feasibility and availability of our proposed multihoming framework are well proved. The framework has also been proved to be applicable in other scenarios such as seamless mobile handover.
