“…The power model aims to calculate the power consumed considering the power of transmission Ptx. It is obviously clear that this assumption is valid due to the strong dependence of the power consumed at macro sites and the traffic load [19]. The value of the parameter L represents the activity level of the BS that allows describing the portion of resources allocated for transmission task, where the no activity of user in current cell is expressed by the value zero and and the resources availability of one or different users represents the full load.…”

“…For the network, total renewable energy at a node is the sum of solar and wind energy available at a node in a day.Output of 1 sq meter of silicon solar cell for a day is 0.28 kW [14].Area of silicon solar panels configured at each node is 100 sq meter. Assuming that solar plants can work 12 hours a day and wind turbines operate all day i.e.…”

“…Similarly in [13], the authors have also proposed to save energy by shutting down idle line cards and chassis, of IP over WDM when the traffic load is low and minimizing the potential traffic interruption when the line cards and chassis are shut down. The authors in [14], also propose an approach to selectively switch off optical links. The key contribution of this paper is to minimize the energy consumption of the whole IP over WDM MLR 14 node network on the basis of total renewable energy available at nodes using an MILP model.…”

Abstract-Power consumption in IP-over-WDM networks has become a major concern, more so due to rapidly evolving data intensive applications. Increasing power consumption also increases the environmental cost (carbon emission). Carbon emissions are the result of power generation using non-renewable (traditional hydrocarbons) energy resources. Usage of non-renewable energy resources (such as hydrocarbons, fossil fuel) is a major cause of global warming. An idea to reduce carbon emission is to maximize the use of renewable energy at each node .This not only gives the opportunity to reduce the carbon emission but also leads to development of sustainable infrastructure. Wind and solar are two important resources of renewable energy today. However, green energy generated by these resources is dependent on time of the day and environmental conditions. Since green energy supply is intermittent and not always available, green nodes are backed up by traditional hydrocarbon grid energy. Efficient use of green energy to minimize carbon emission and energy cost is a challenge. We propose MILP (mixed integer linear program) that minimizes the overall non-renewable energy consumption of the MLR WDM network. This MILP model uses mixed-line-rate (MLR) over the single-line-rate (SLR) in WDM. We also compare the non-renewable energy consumption of MLR-WDM network with that of SLR-WDM network. Optimization results indicate that proposed MILP can reduce the overall non-renewable energy consumption of the network up to 35%. In addition, it also reduces the number of transponders used in MLR as compared to SLR networks. Since the number of transponders utilized in the optical layer is directly proportional to the power consumed, therefore with MLR network, non-renewable energy consumption can be reduced in comparison to SLR network.

Abstract-The power consumption in Information and Communication Technologies (ICT) networks is growing year by year; this growth presents challenges from a technical, economic and environmental point of view. This has lead to a great number of research publications on 'green' telecommunication networks. In response, a number of survey works have appeared as well. However, with respect to backbone networks most survey works (a) do not allow for an easy cross-validation of the savings reported in the various works, (b) nor do they provide a clear overview of the individual and combined power saving potential. Therefore, in this work we survey the reported saving potential in IP-over-WDM backbone telecommunication networks across the existing body of research in that area. We do this by mapping more than 10 different approaches to a concise analytical model, which allows us to estimate the combined power reduction potential. Our estimates indicate that the power reduction potential of the once-only approaches is 2.3× in a Moderate Effort scenario and 31× in a Best Effort scenario. Factoring in the historic and projected yearly efficiency improvements ("Moore's law") roughly doubles both values on a 10-year horizon. The large difference between the outcome of the Moderate Effort and Best Effort scenario is explained by the disparity and lack of clarity of the reported saving results, and by our (partly) subjective assessment of the feasibility of the proposed approaches. The Moderate Effort scenario will not be sufficient to counter the projected traffic growth, although the Best Effort scenario indicates that sufficient potential is likely available. The largest isolated power reduction potential is available in improving the power associated with cooling and power provisioning, and applying sleep modes to overdimensioned equipment.
