I am a PhD candidate in Computer Science at School of Computing, National University of Singapore (NUS). I am advised by Prof. Roger Zimmermann and my work interest is on Video Streaming Architecture, Content Delivery, Multimedia Systems, and Computer Networks. I am a member of Media Management Research Lab and working on Streaming Media project. I design and develop a novel suite of Adaptive Bitrate (ABR) solutions to address the key challenges of video delivery including quality instability, unfairness, and network resources under/over utilization for HTTP Adaptive Streaming (HAS) and HAS-like (DASH) systems. I am fortunate to work with an exceptional collaborator Prof. Ali C. Begen.

Current Main Projects

Centralized-based ABR Solutions

We investigate how a central entity like Software Defined Networking (SDN) controller assist the video players in their bitrate selection and bandwidth allocation. Such central entity has a general overview and control over the network, and thus an appropriate ABR decision will be taken by the players.

Distributed-based ABR Solutions

We investigate how a distributed rules (e.g., game theory, queuing theory, and multisource/multipath mechanism) can be leveraged by the client-driven ABR scheme. Thus, the set of video players cooperate and coordinate among themselves to achieve their common objective (i.e., maximizing the viewer QoE) without any implicit or explicit signaling messages.
