Green Communication Network:
The communication networking which are energy productive with respect to environmental issues are generally termed as green networking. Research field focus at maximizing performance of communication systems. Pattern is now rapidly shifting towards how to produce sufficient performance with low energy expense.
APPLICATION AND USES OF GREEN COMMUNICATION
Because of the rapid growth of the Internet and lower price of computer hardware leads to requirement in development of different types of applications from different field.
GREEN COMPUTING IN INFRASTRUCTURAL NETWORK
we know that data centers are becoming one of the major consumer of electricity in the industrialized world and it will rise even higher. like cooling and power conversion.
1-Bandwidth shared among data centers
Data centers mainly provision higher workload, and often run properly below capacity. Congestion in network changes daily which is basically based on the application used but most of the time congestion are fulfilled by a subset of the network links and switches.
The different bandwidth mechanisms and their uses are:
Fair-Share Bandwidth allocation
- Bandwidth Capping
- Second Net
2- Memory storage in cloud
Cloud computing is expanding technologies in the computing industry.In cloud computing, End-user generates a service request for choosing memory of service based resources that are needed. A transparency mechanism is given in which it let the users to access memories where multiple memories of several resources appear to the user as a single unit.
GREEN COMPUTING IN WIRELESS NETWORK
Wireless systems, which include the development of cellular networks and cellular 4G phone have been executed. Green communication is becoming more focused, for lower radiation and low communication expense.
Green antennas for low radiation in Cellular Network
Peer-to-Peer (P2P) wireless network like Wireless Sensor Networks (WSN)&Ad Hoc developing rapidly. Techniques that depend on P2P networks lacks energy. So, the problem of minimum energy tops the list. The Green Cellular Green Antennas are established to reduce the transmission power of Mobile stations.
LATEST TREND IN GREEN COMMUNICATION
“Fiber everywhere” are endeavor to improve connectivity and address demand increases from the use of high quality video, 3 G/4 G and other broadband service sand the solution was investments and activity.
Green communications technologies are accountable for carbon footprint generated by human activity. This increases the need to focus on these. Green communication is doing just that. .Environmental friendly batteries, renewable energy resources are the proposed solutions.
ENERGY EFFICIENT DEPLOYMENT ARCHITECTURE
In the next generation of mobile communication systems, the net transmit power needed per transmitted bit is anticipated to be lowering fair amount.Both the 3G LTE and IEEE 802.16 m standards consolidate a different property and techniques that increases spectral productivity and energy efficiency and extend the communication range.
RENEWABLE ENERGY RESOURCES
Renewable energy resources play an important role in reducing CO2 gas emissions. Solar power & wind energy can usefully accompany and reduce the net electrical power consumption from the grid. Also, these resources can help power remote The BS sites are the area where the electricity grid is mostly notavailable. This will help in reducing CO2 emissions.
Molecular communication is an emerging pattern where bio-nano machines.(for example: artificial cells, genetically engineered cells) communicate to perform function. The benefits of this “molecular” approach to communications are size,bio compatibility, and bio-stability. Examples of applications are DDS(drug delivery system), bio-hybrid plants, and LoC(lab-on-a-chip)systems.
ADVANTAGES OF GREEN COMMUNICATION
- No harmful emissions emitted in air.
- Certain areas can be benefited economically.
- Less amount of money is spent because of less maintenance.
- It is renewable as it never runs out.
- Reduces global warming as it reduces carbon dioxide emissions.
DISADVANTAGES TO ADOPTING GREEN COMMUNICATION
- Implementation costs are high.
- Lack of information.
- No known alternative chemical or raw material inputs.
- No known alternative process technology
- Uncertainty about performance impacts
- Lack of human resources and skills.
