| Outline of Final Research Achievements |
We studied a Mobile Data Offloading Protocol (MDOP) which delays the delay tolerant contents to balance the load of cellular infrastructures. MDOP balances the load in view of time, place and link by considering the load of base station, mobility of the users and delay tolerant of the contents. From the detailed evaluation results, it was confirmed that the time and place-wise offloading was able to send more data by staying user in high load eNBs, send more data at low load eNBs, and peak shift of mobile traffic localities by using delay tolerant data. Regarding evaluation environment for large scale networks, we also developed a high fidelity evaluation environment made by the combination of a network simulator and virtual machines with virtual wireless LAN devices. A network simulator and virtual machines also solve the cost for nodes, the ease of field preparation, and the reproducibility of radio propagation by modeling evaluation environment.
