SpeedBalance: Speed-scaling-aware optimal load balancing for green cellular networks

—This paper considers a component-level deceleration technique in BS operation, called speed-scaling, that is more conservative than entirely shutting down BSs, yet can conserve dynamic power effectively during periods of low load while ensuring full coverage at all times. By formulating a total cost minimization that allows for a flexible tradeoff between delay and energy, we first study how to adaptively vary the processing speed based on incoming load. We then investigate how this speedscaling affects the design of network protocol, specifically, with respect to user association. Based on our investigation, we propose and analyze a distributed algorithm, called SpeedBalance, that can yield significant energy savings.
