Adaptive Application for Mobile Network Environment

In a mobile network environment, a Mobile Router (MR) has multiple communication interfaces to the Internet. It switches between or simultaneously uses these interfaces, causing network conditions within the MR to change. If the network conditions were shared with between nodes behind the MR (MNN) and their correspondent nodes (CN), it would be possible for applications to change its behavior accordingly. In this research, an application that has this ability is called Adaptive Application. We propose a new architecture of Adaptive Application, which allows allocating IDs to communication interfaces of MR and distributing those IDs to both CN and MNN. MNN and CN can be informed of the interfaces currently used on the MR. In a mobile network environment, a communication interface is a big determining factor in network conditions. This thus allows applications to adapt to network conditions. We also expose evaluation results obtained from a videoconference system that implements the proposed architecture. This application reacts to changes in the currently used interface and dynamically modifies its transmission rate. Finally, we conclude that dynamic adaptability of applications to the current network condition could be effective.
