2018 VII International Conference on Network, Communication and Computing

(ICNCC 2018)

December 14-16, Taipei

Keynote Speakers

Prof. Daping Chu

University of Cambridge, UK

About: Professor Chu’s research activity has been in the areas of both theoretical and experimental condensed matter physics, semiconductor devices and materials, nanostructures and properties, ferroelectrics non-volatile memory devices, organic electronics and inkjet fabrication process. His current research includes space light modulation using holography for true 3D displays, digital illumination and optical communications. Combining 3D image reconstruction with full parallax and occlusion effects and spatial interactions in spectrum and time domains will provide participants the immersive experience which never exists before. This is now being explored through research work to increase both spatial and temporal bandwidths and development of new approaches to best utilise the existing technology. Energy saving, in particular in the built environment, presents a new challenge to electronic/photonic for innovative new technologies. Professor Chu’s research is focusing on the means for both the active modulation of the spatial profile and impact of lighting and the passive control of solar shading and radiation. Various successful approaches, including laminated electro-active foils (LEAFs) for retro-fitting and development at fundamental level of new devices and materials have been demonstrated.

Title: Wavelength Selective Switchesfor Software Defined Networks and Data Centres

Abstract:The high demand on the data traffic in modern optical communication networks pushes the backbone of the network for long distance data communication to all optical with the information kept in the optical domain in a wavelength division multiplexing (WDM)manner throughout the network until it reaches its final destination. It also requires dynamic routing and flexible definition of the network connectivity. This talk will review the advantages of holographic programmable wavelength selective switch (WSS) based on liquid crystal on silicon (LCOS) light engine as a key enabling technologies for software defined reconfigurable all optical networks, followed by the introduction of a new stacked WSS architecture to allow the WSSs to be reconfigured as ultra-high port count switches or non-blocking wavelength cross-connects (WXCs). Finally, it will address how this stacked WSS architecture can be utilized to meet the optical switching demand in large-scale data centres.

Title: Free-Space Optical Communications: Modeling and Performance Evaluation

Abstract: The data transmission rate, range, and reliability of free-space optical communication (FSO) systems are affected by a number of atmospheric phenomena, such as rain, haze, fog, snow, and scintillation. Thick fog with over 300 dB/km of attenuation limits the link length to around 100 m. Even under clear air conditions with no atmospheric scattering, the FSO communication link still suffers from fading due to scintillation. Scintillation fade margins are 2 to 5 dB for FSO links of 500 metres or less, which is well below margins for the atmospheric attenuation. For the link range beyond 1 km, scintillation may severely impact the performance of FSO links, thus resulting in the link deterioration, i.e., higher outage probability and ultimately complete link failure. In this presentation the performance of terrestrial FSO system under various channel conditions, such as fog, sandstorm, and turbulence, will be investigated and analysed. The results are theoretically and experimentally compared with the existing channel models.

Title: Energy Efficient Streaming for Smartphone by Video Adaptation and Backlight Control

Abstract: Smartphone becomes an indispensable gadget in our daily life. Prolonging battery life on smartphone can extend the usability of the phone without being recharged, especially for accessing streaming video, which is a paramount service in the mobile Internet era. Many researchers have proposed energy efficient streaming methods, including bandwidth control and packet scheduling. Such studies have focused on reducing the energy consumption of central processing units (CPUs) and wireless networks; however, screens may drain substantial energy on smartphone. In this study, an energy efficient streaming sys- tem is proposed, combining adaptive coding and a backlight control mechanism. A non-parametric signal prediction is used to predict the network condition and then some adaptive encoding parameters are subsequently adjusted to fit the network capability. A histogram equalization is applied to compensate for the loss of image contrast after reducing the backlight. To validate the proposed concept, some experiments were conducted and the corresponding results show that the proposed streaming system can effectively reduce energy consumption on smartphone, while accessing the video streaming service.
