Research Themes

My main research interest is to achieve sustainable social systems under the competitive behavior among individuals. I usually utilize mathematical models, e.g., Integer linear programming (ILP), for optimal system design, and game theoretic approaches for distributed control. The following are examples of recent research themes.

Selfish yet Optimal Control based on Game Theoretic Approaches

Selfish yet Optimal Routing in Road Networks
Selfish yet Optimal Service Chaining in NFV Networks

Network Optimization for Large-Scale Content Distribution

ILP-based Optimaility Analysis of BitTorrent-like P2P Content Distribution

Human-Harmonized Automatic Evacuation Guiding and Risk Analysis using Geographical Big Data

Automatic Evacuation Guiding based on Implicit Collaboration among Evacuees, Mobiles, Network, and Edge Server
Route Selection for Speedy, Safety, and Capacity-aware Evacuation
Road Network Risk Analysis using Geographic Big Data

Vulnerability Analysis of Competitive Information Diffusion

Epidemiology-inspired Vulnerability Analysis of Competitive Pull-based Broadcast

Distributed Cooperative Control for Large-Scale IoT Networks
