  Wireless networking allows users to access information and services
regardless of location and physical infrastructure. It is a fast growing
technology due to its availability of wireless devices, flexibility, ease of
installation and configuration. With this rapid expansion of information and
Communication Technology (ICT), the consumption of energy is also increasing.
In the early age of wireless technology, computing infrastructure focused on
everywhere access, capacity and speed of technology. But now computing
infrastructure should be energy efficient because, in wireless networking,
devices are mostly powered by a battery that is a limited source of energy and
is a challenge for the researchers. In computing infrastructure energy saving
and environmental protection has become a global demand. This paper proposed a
computing infrastructure based on green computing for energy efficient wireless
networking. Further, some challenges and techniques like power consumption in
network architecture, algorithm efficiency, virtualization, and dynamic power
saving will be discussed to make energy efficient computing infrastructure.
