The amount of energy spent for network infrastructures can be significantly reduces using energy-aware protocols. This in turn can reduce CO2 emission in order of million metric tons. Recently, the idea of energy conservation in network infrastructure has been presented in a number of works. However, thus far, less attentions are given on power-conserving issue for optical networks. Our research focus is to design new architectures and protocols to improve energy consumptions of optical networks. We are currently working on a number of approaches:
1- Using Optical Burst Switching as an underlying switching mechanism to reduce energy consumptions.
2- Designing an energy-aware approach to improve overall energy consumption of optical nodes.
3- A number of works in wireless sensor networks have suggested cluster-based energy-adaptive MAC protocols to conserve total network energy requirements. Similar approach can be used by utilizing bundle layer in optical networks.
