摘要:

物联网(IoT)的持续发展催生了对高效通信方案的迫切需求。随着物联网用户生态系统不断扩张,传统通信协议在满足其日益增长的需求方面面临严峻挑战,包括能耗、可扩展性、数据管理与干扰问题。针对这一现状,无线能量传输与数据传输的融合已成为一种颇具前景的解决方案。本文研究了一种面向能量收集(EH)的数据传输方案:一组用户由各自的多天线功率信标(PB)供电,随后使用不规则时隙ALOHA(IRSA)信道接入协议向基站(BS)传输数据。我们提出了一个闭式表达式来建模该方案的能耗,在无线能量信道中采用平均信道状态信息(A-CSI)波束成形技术。随后,我们采用强化学习(RL)方法,每个用户都作为一个智能体,其任务是找到最高效的重传策略。该策略的制定同时考虑了用户的能量约束以及需要传输的最大数据包数量。我们的研究结果证实了该方案的可行性,尤其是当功率信标(PB)可被策略性部署以确保与用户建立强视距连接时,更凸显了优化部署的潜在效益。

英文摘要:

The evolving landscape of the Internet of Things (IoT) has given rise to a pressing need for an efficient communication scheme. As the IoT user ecosystem continues to expand, traditional communication protocols grapple with substantial challenges in meeting its burgeoning demands, including energy consumption, scalability, data management, and interference. In response to this, the integration of wireless power transfer and data transmission has emerged as a promising solution. This paper considers an energy harvesting (EH)-oriented data transmission scheme, where a set of users are charged by their own multi-antenna power beacon (PB) and subsequently transmits data to a base station (BS) using an irregular slotted aloha (IRSA) channel access protocol. We propose a closed-form expression to model energy consumption for the present scheme, employing average channel state information (A-CSI) beamforming in the wireless power channel. Subsequently, we employ the reinforcement learning (RL) methodology, wherein every user functions as an agent tasked with the goal of uncovering their most effective strategy for replicating transmissions. This strategy is devised while factoring in their energy constraints and the maximum number of packets they need to transmit. Our results underscore the viability of this solution, particularly when the PB can be strategically positioned to ensure a strong line-of-sight connection with the user, highlighting the potential benefits of optimal deployment.
