Constructing Power-Aware Multicast Virtual Networks
Ning Qi, Bin Qiang Wang, Bo Yuan, Bo Zhang · Advanced materials research · 2011
Power consumption of Internet is becoming more and more a sensible problem, which is of interest for both the research community and the general public. In this paper we have formally defined the power-aware multicast VN construction problem and setup an ILP model whose objective is to find a virtual topology on top of substrate network fulfilling all restrictions, while the power consumption of construction is minimized. In order to address the problem efficiently we develop a greedy algorithm: PMVNMH. The efficiency of the power-aware construction algorithm is evaluated by emulation experiment.
