Communication devices and their networks have become very popular in our daily life. The communication technology is now used in various devices, from mobile phones, smartphones, tablets, and wearable computers to household electric equipment such as game machines, microwave ovens, and refrigerators, or even unmanned aerial vehicles and environmental observation devices. Furthermore, networks which connect communication devices become more diverse. For example, we have optical fiber networks, wireless access networks, cellular networks, satellite networks, and vehicular networks. In addition, we also have ad hoc networks, sensor networks, and so forth. However, are we efficiently utilizing those communication networks? Can we further improve the abilities of such networks? In this laboratory, we are not only focusing on next generation networks and building our research based on theoretical design of networks and protocols in order to optimize the communication networks, but also emphasizing on professional human resources development. The main keywords of our research themes are as follows.

1. Unmanned Aerial Vehicular (UAV) networks
2. Satellite networks
3. Intelligent Reflecting Surface-aided communication systems
4. Optical and wireless integrated networks
5. Resilient networks
6. Machine learning, Deep learning based network control
