Major Research Contributions and Significance of Their Impact and Influence

As many new types of devices will be connected to networks in the future, it is very important to provide ubiquitous networking and services capabilities through seamless interconnection between humans and objects. I have targeted to find a good way for solving various problems due to lack of trust while developing advanced technologies for intelligent autonomous networking and services.

One of the ultimate objectives of my research is to meet the challenge of seamless communications of “anything” (e.g., humans and objects). So, I have been developing key technologies to encompass the following: Ubiquitous Connectivity, Pervasive Reality and Ambient Intelligence (CRITech). These technologies improve the quality of our daily life and provide significant social-environmental impact.

To date, the following research contributions have been made. 

• New architecture (i.e., knowledge plane) design for future of networks to support “smartness” and semantic alarming mechanisms for autonomic network control and management through context awareness. 

• Integrating social networks and IoT to enhance the quality of everyday life through collaborating social objects with object-to-object communications and trust-based recommendation engine for intelligence middleware based on human-object relationships.

• Novel service platform and control mechanisms for various applications (e.g., smart homes/buildings, smart city, Intelligent Transport System, Smart Grid, etc.) using smart objects considering constraint environment in terms of energy consumption.

• Mobile multimedia and N-screen services through user friendly localization system and cloud-based decision making to support distributed intelligence for future smart homes.

• Energy aware networking with active and sleep mode operations for energy efficiency of networks and its performance evaluation.
