Below are some recent news.

Congratulations to the team ! Our paper “A Survey of Wearable Devices and Challenges” is accepted to IEEE Communications Surveys and Tutorials !

Congratulations Benoy ! Our paper “e-DASH: Modelling an Energy-Aware DASH Player” is accepted to IEEE WoWMoM 2017.

I was awarded “Malcolm Chaikin Prize” for Research Excellence in Engineering at UNSW for 2015. The prize is awarded for the best thesis (high quality thesis, strong ability to convey the excitement of his field of research to the scientific community and raising the profile of Engineering to the community at large) in the calendar year.

Our paper “AFV: Enabling Application Function Virtualization and Scheduling in Wearable Networks” is accepted to Ubicomp 2016 !

Our paper “TransFetch: A Viewing Behavior Driven Video Distribution Framework in Public Transport” is accepted to LCN 2016 !
