Abstract

The objective function for Energy optimization is the amount of information transmitted per unit of energy, replacing the amount of information transmitted per unit of time (i.e., throughput). Here it is clearly stated that the given existing diversity of power consumption figures among mobile devices, performing a fair allocation of resources among devices is challenging. We propose a criterion to objectively balance between the most energy-efficient configuration (where all resources are given to the single most energy efficient device) and the throughput-optimal allocation (where all devices evenly share the resources regardless of their power consumption).In this work we first propose a new energy-based criterion, the EF criterion, to define a trade-off between the most energy-efficient configuration (where all resources are given to a single device) and the throughput-fair allocation (where all devices evenly share the resources regardless of their power consumption). We then address the case of wireless LANs, based on a performance analysis model for their energy consumption.
