Multi-State Energy Efficiency Improvement Strategy for DRX Functional Devices

EasyChair Preprint 6738

Abstract

Ensuring the high efficiency of communication is one of the important properties of the Internet of Things (IoT) device network, which can be realized by Discontinuous Reception (DRX). In this paper, a strategy is proposed to schedule the user equipment (UE) with the base station knowing whether the packet is coming in the following 1 or 3 time slots, and this mechanism is added to an IoT device model with DRX function. This model operates on 5G standards and communicates with base stations. Packets are generated with a fixed length and a Poisson process. Based on this assumption, according to the cross-layer analysis model, this paper analyze 1) the steady-state probability of each state, 2) the energy efficiency of this model, and 3) the improvement of energy efficiency relative to that of the single-mode circuit. It can be observed from the theoretical and simulation results that this model can improve the energy efficiency on the basis of the original strategy.
