Lab Introduction

Cyber-Physical Systems (CPS) Lab researches computing systems interacting with Physical, real environments, considering in Cyber-Security and the Future Internet. The current research includes (i) CPS supporting the safe and efficient driving in transportation systems (e.g., road networks) in real life, (ii) CPS protecting and monitoring efficiently transportation systems (e.g., road networks and subways) and people (e.g., drivers, passengers, and pedestrians) in emergency situations (e.g., wars, accidents, and disasters), and (iii) Cyber-security in CPS to make CPS more reliable and trustable under harsh conditions, such as CPS nodes' malfunction and adversaries' attacks.

Ongoing Research

1. Vehicular Networks

We are working for the data forwarding schemes for unicast and multicast in vehicular networks. We take the forward-and-carry approach because the vehicular networks includes Vehicular Ad Hoc Networks (VANET) that are Disruption Tolerant Networks (DTN). As the unicast data forwarding schemes, we have developed (i) Trajectory-Based Data Forwarding (TBD) for Vehicle-to-Infrastructure (V2I), (ii) Trajectory-Based Statistical Forwarding (TSF) for Infrastructure-to-Vehicle (I2V), and (iii) Travel Predication-Based Data Forwarding (TPD) for Vehicle-to-Vehicle (V2V).

2. Road Sensor Networks

We are working for fundamental techniques for Road Sensor Networks. As a prerequisite function for sensor networking, we have developed a localization for road sensor networks called Autonomous Passive Localization (APL). For the road network surveillance, we have developed a sensor scheduling algorithm called Virtual Scanning Algorithm (VISA).
