To support mobile/wireless networking environment, we consider a mobile router which is connected via dual interfaces with WiBro (i.e., Mobile WiMAX) and high-speed downlink packet access (HSDPA) in a moving vehicle. The mobile router can support multihoming features using the extended version of mobile IP (MIP) protocol for multiple interfaces. In our multihoming environment, we propose the dynamic interface selection mechanism using policy routing to provide redundancy and fault tolerance. The proposed mechanism decides the preference of interfaces and checks the availability of selected interface in dynamic interface selection agent. Our proposal aims to achieve benefits of interface selection according to flow characteristics and automatic interface reestablishment against link failure, etc. We also show some experimental results.
