Our research direction is guided by our desire to bridge the digital divide by seeking practical and effective technologies to overcome barriers. For example, we focus on wireless Internet as a solution in the rural areas which can be set up and put into operation with limited cost.

In particular, in order to provide rural connectivity, we pay attention to Internet on satellite which we are an active member of the AI3 (www.ai3.net) testbed and Wireless Mesh as well as Mobile Ad Hoc Networks. In addition, we are interested in the issue of practical deployment of MANET in post-disaster environment, as in our project called D.U.M.B.O.

Moreover, we are interested in creating fair opportunity for those the “have not” in accessing rich contents consuming high bandwidth over heterogeneous networks. We concentrate on pushing streaming multimedia content from high speed network to a relatively narrow bandwidth network for those in the “have not” part of the Internet.

This is addressed by our research project called ANGKOR which narrow 30Mbps DVTS stream sent from France to 6 MBps as received via a satellite link in Cambodia. The research output DVRelay of this project has been applied to CanalAVIST and is now well-known among Asia-Pacific networking community.

Our research methodology concentrates on system design and implementation targeting at producing solutions which are easy to deploy while sustainable under resource limited conditions. As much as possible, we do field tests in real world environment to provide a proof of concept.
