GM-PAB: A Grid-Based Energy Saving Scheme With Predicted Traffic Load Guidance for Cellular Networks

Free registration required

Executive Summary

In cellular networks, the base station power consumption is not simply proportional to the traffic loads of its coverage. As the traffic load fluctuates spatially and temporally, the base stations consequently suffer from heavy energy wastage when the traffic loads of their coverage are low. In this paper, the authors propose a grid-based energy saving scheme over predicted traffic loads. They firstly take advantage of the spatial-temporal pattern of traffic loads and employ the compressed sensing method to predict the future traffic loads. Then, they propose a grid-based energy saving scheme to improve the energy efficiency through turning some base stations into sleeping mode while ensuring the quality of service.
