Prof. Der-Jiunn Deng: ‘QSHINE is the primary venue focusing on heterogeneous networking’

After receiving the Ph.D. degree in electrical engineering from the National Taiwan University in 2005, Dr. Der-Jiunn Deng joined the National Changhua University of Education (Changhua City, Taiwan) as an assistant professor in the Department of Computer Science and Information Engineering in August 2005 and then became a full professor in February 2012. His research interests include multimedia communication, quality-of-service, and wireless networks.

He will serve as General Chair at the 11th International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness (QSHINE 2015). We talked to him about the upcoming conference and the developments in the field of mobile networks.

What makes QSHINE unique?

Heterogeneous networks is a rapidly emerging field of activity and has received a lot of attention recently, due to its improved coverage and capacity gains. These promising gains are urgently required to facilitate mobile computing with the booming of mobile Internet devices. Evolving of Heterogeneous networking technologies have focused on multiple aspects in terms of data rate, security, efficiency, QoS/QoE, etc. As the only conference focusing on heterogeneous networking, QSHINE has been established as the primary venue for researchers and practitioners to disseminate, exchange and discuss all recent advances related to heterogeneous networking, particularly for quality, experience, reliability, security and robustness.

What insights emerged from last year’s conference?

Future gains of mobile networks will be obtained more from advanced network topology, which will bring the network closer to the mobile users. As various radio access technologies and multi-mode terminals incorporating multiple network interfaces appear, wireless heterogeneous networks can be deployed to improve spectral efficiency. These networks use a mixture of different type of wireless networks to potentially improve spatial reuse and coverage by allowing future mobile networks to achieve higher data rates, while retaining seamless connectivity and mobility for mobile user. For example, recently, 3GPP TSG RAN plenary approved the study item on “Licensed-Assisted Access using LTE”. Hence, the new WLAN MAC shall have flexibility to support possible spectrums sharing such as WLAN as cognitive radios under multiuser PHY and provide smooth vertical handover, good network economic efficiency, and spectrum sharing efficiency.

The 11th edition of QSHINE will focus on innovative and intelligent infrastructure for the future networks. Why this focus and why now?

Future networks are visualized as networks that consist of more than one type of network systems, and the modern infrastructures are large-scale, complex and highly networked systems, which require innovative and intelligent ICT solutions to provide efficient and sustained service. QSHINE 2015 focuses on the topic of innovative and intelligent infrastructure for the future networks to seek out novel innovative and intelligent methods for the operation and control of future infrastructures.

What are the main challenges researchers in the area of heterogeneous networking struggle with, at the moment?

To ensure the QoE guaranteed services delivery in heterogeneous wireless networks, there is a critical need for research into new designs and implementations that can make networks more reliable and secure from a system point of view. In the future, heterogeneous wired/wireless networks deployment will exhibit complementary benefits that can be leveraged for efficient integration, and users can further enjoy seamless and secure connectivity when roaming between different wireless networks. The trend towards integrated use of multiple radio access technologies and networks will be essential for addressing the challenges faced by mobile networks.
