Equal Area User Clustering Algorithm for Energy Efficient Cellular Network

This work proposes a novel approach that will assist in delivering significant energy efficiency gains in wireless networks. The algorithm cluster users into equal area circular tracks between concentric circles in a given cell. If the number of users in the outer circular track is below some threshold value, the track is made to be switch off. So that the transmit power will be adaptively adjusted accordingly since it has direct relationship with the distance. The impact of this approach on achieving energy-efficient wireless communication systems is discussed. Reduced Okumura-Hata model formula has been used for propagation issues and power calculations. From simulation result, it has been shown that up to 17dBm power can be saved for ten scans. In other words, the energy efficiency can be maximized up to 20-30%.
