With the rapid development of Iot & Cloud services, the increasing power consumption is becoming a problem. Therefore, this theme is mainly about how to minimize the power consumption of data center. The power consumption is mainly consisted of ICT Machinery, the air conditioner, and the power supply. Especially, the power consumed by ICT Machinery and air conditioner is combined mutually. Therefore, we implement the AI to learn its behavior, aiming to minimize the power consumed by air conditioner by optimizing the server load distribution. Also, we also do several researchs focusing on, instead of traditional air cooling and water cooling, cooling the server by immersing it in non-transfer fluid.

AI is applied in several Web Service aiming to enhance the efficiency and functionality. AI excels at recognizing the features of data which can hardly be recognizied by human, and has the potential to surpass the existing technology. This theme is mainly about how to make use of the advantages of AI. Specifically, let AI learn the access pattern to optimize the placement in storage, which is so-called Hot/Cold Tiered storage system. Another theme is about smart office technology, which could collect information such as the heart rate and temperature of people in this office, based on which could optimize the Air conditioning option. Another theme is, by learning the access information of server, preventing the various attacks.

The Internet of Tings(IoT), which creates new value by connecting everything to the Internet, sending and recieving information, and managing it, is rapidly developping.Edge computing, in which servers are distributed near a device, is attracting attention as a method of processing a large amount of information emitted by these IoT devices. This theme is mainly about achieving the low power consumption and low latency of edge computing system by optimizing the task arrangement. In particular, we are focusing on Osmotic Computing, a method that distributes tasks based on the principle of osmotic pressure.

In recent years, with the increasement of smart phone & IoT Machinery, the amount and type of network traffic has been increasing rapidly. To conquer this problem, Network Function Virtualization(NFV),as one of the keys to this problem, emerges. In NFV, it is necessary to perform function allocation, resource allocation, route allocation, and etc. appropriately and dynamically. Our research group proposes a method to achieve them by modeling highly autonomous distributed and self-organized biochemical mechanisms.
