ENERGY EFFICIENT SOLUTIONS FOR GREEN CELLULAR NETWORKS – A SURVEY

In recent years, Energy – Efficiency in Cellular Networks is an important concern for network operators. The growing awareness of Energy – Efficiency as well as economic concern of network operators provides the new technologies in designing Green Cellular networks. The green cellular network has become the most popular research topic for the future. The Energy – Efficiency solution can be achieved by improving the design of certain hardware or by providing renewable energy sources (RES) like solar or wind. According to the technical analyst, the Base Stations (BSs) are the most energy intensive part of the Cellular Network. As the BSs consume more power of the total energy used in cellular network, a survey on techniques to obtain energy saving in BSs and powered by renewable energy sources in the area where there is no public and stable power supply to obtain the Green Cellular Networking is considered first. In this survey, the realities which gives the importance of green mobile networking and review of the existing methods to obtain Energy – Efficiency is presented.
