Collaborative research by Prof. Kyoungsoo Park, Prof. Yung Yi, and Prof. Song Chong received a wide coverage in major media outlets in Korea. Their research is on the development of cellular data offloading platform. It has recently been accepted to ACM MobiSys 2015 (AR=13.2 %), one of the major international conferences in the fields of mobile systems, and is to be presented in May.
A novel mobile network platform has been developed, which can maximize opportunistic Wi-Fi network usage when downloading contents using smart mobile devices.
Even though the number of Wi-Fi available spots has increased, once the user leaves the coverage of a specific Wi-Fi access point (AP), he/she has to manually connect to other available APs. However, using the new platform they proposed, the devices can automatically handle re-scanning of APs and thus maximize the Wi-Fi network usage. Furthermore, they developed a technology that allows “download reservation” with a user-specified deadline. Using this technology, the content is made ready by the time the user specifies, using minimum cellular traffic via flexible control between opportunistic Wi-Fi and cellular network usage.
