Abstract

In this work, the optimal resource allocation for a zero-energy device network with quality of service requirements is investigated, aiming to minimize the average energy consumption. Under these considerations and accounting for the circuit power consumption of the devices' hardware, the employment of slotted ALOHA for the uplink data transmission is examined. The derived non-convex optimization problem is transformed into an equivalent convex problem in order to be optimally solved in polynomial time. The solutions of the optimization problem are then given in closed form. Finally, simulation results demonstrate the optimal resource allocation strategy of the zero-energy device network. Notably, taking into account the circuit power consumption leads to a more energy efficient resource allocation scheme.
