A Survey on Energy Efficiency for Wireless Mesh Network

Reduction of CO2 emissions is a major global environmental issue. Over the past few years, wireless andmobile communications are becoming increasingly popular with consumers. The Most popular kind ofwireless access is known as Wireless Mesh Networks (WMNs) that provide wireless connectivity throughlot cheaper and more supple backhaul infrastructure relative to wired solutions. Wireless Mesh Network(WMN) is a new emerging technology which has been adopted as the wireless internetworking solution forthe near future. Due to higher energy consumption in the information and communication technology (ICT)industries, and which would have an impact on the environment, energy efficiency has become a key factorto evaluate the performance of a communication network.This paper primarily focuses on the classification layer the greatest existing approaches devoted to theconservation of energy. It is also discussing the most interesting works on energy saving in WMNsnetworks.
