Energy Conservation

Bloc A, room 811, Byblos campus / Nicol 222, Beirut campus.

The Computer Science and Mathematics Department is organizing a talk on “Energy Conservation in Next-Generation Passive Optical Access Networks (NG-PONs).” It will be conducted by Dr. Ahmad Dhaini.


NG-PONs has been considered in the past few years as a promising broadband access technology. With the ever-increasing power saving concern, energy conservation has been a major theme in its operations. In this talk, we first discuss various techniques aiming to resolve this important issue. We then represent a new framework for the implementation of Green Bandwidth Allocation (GBA) in NG-PON. The proposed framework is able to achieve high energy saving without violating the quality-of-service requirements for all types of traffic.


Dr. Ahmad Dhaini received his B.Sc in Computer Science from the American University of Beirut (AUB), Lebanon in 2004. He holds a Master’s degree in Electrical and Computer Engineering from Concordia University, Montreal, with a best thesis award nomination in 2006. He also holds a Ph.D. in Electrical and Computer Engineering from the University of Waterloo, Canada (2011).

Dhaini is the winner of the National Sciences and Engineering Research Council of Canada (NSERC) Postdoctoral Fellowship, the Ontario Graduate Scholarship in Science and Technology (OGSST), and various teaching and research awards at University of Waterloo. He is currently a Postdoctoral Fellow at Stanford University, working in the Photonics and Networking Research Laboratory (PNRL). In 2011-2012, he was a Research Associate at University of Waterloo, and a Consultant at KAUST, Saudi Arabia. He worked as a Software Consultant at TEKSystems, Montreal, in 2006-2007; and as a Software Designer at Ericsson, Montreal, in 2007-2008. He has authored a book, and authored/co-authored more than 15 papers in major journals and conferences related to broadband access networks.

 All are welcomed to attend.
