Green Communication Using CoMP in Heterogeneous Wireless Network

Abstract

Energy efficiency in cellular networks is a growing concern for cellular operators to not only maintain profitability, but also to reduce the overall environment effects. According to researcher, the base stations are the most energy intensive part of a typical cellular network. In a cellular wireless network power consumption is the biggest issue. With global warming and energy crises becoming the most compelling challenges for the environment green solutions is a common problem to be tackled. Hence the primary focus of the Green cellular network is improvement of energy efficiency and integration of the network infrastructure and network services to enable the network to require less power to operate and reduced carbon emissions to care for planet. Saving power in base stations is therefore the primary focus in energy efficient operation. The main goal of energy efficiency is for saving and reducing power consumption while guaranteeing QoS. As mobile traffic is increasing new applications are raising expectations for higher data rates creates heterogeneous network by introducing low power nodes is an attractive approach to meeting traffic demand performance and energy efficiency. According to researchers, the energy efficiency of cellular network can be improved at component level link level and network level. There is lots of literature available on energy efficiency at component level link level and network level without coordination. The energy efficiency can also be achieved by coordinated transmits and receive at network level this can be achieved by power saving protocols, energy aware cooperative base station power management cell zooming link adaptation and beam-forming with CoMP. This attempt will review existing CoMP solutions towards energy efficient architecture and network deployment. newline The heterogeneous network is an attractive approach for meeting traffic demands of future communication system. Participation of different types of BSs in heterogeneous network increases interference on each other
